Jessica Simpson: My Wedding Date Is Set!

She may not have found a wedding dress yet, but Jessica Simpson can cross another important item off her to-do list: setting her wedding date!

"I'm still trying to figure out what to wear! I don't know if I want the big boom, or the curvy thing, but it will be something beautiful," the Style Icon of the Year said at Us Weekly's Hot Hollywood party at L.A's Eden on Tuesday. "I kind of have a couple ideas in my head, and I have a date; I'm really excited!"

Engaged to former NFL player and Yale grad Eric Johnson, 33, since November, the 30-year-old singer -- clad in an Etro dress and Giuseppe Zanotti shoes -- told Us she isn't worried about slimming down before the big day.

"I just have to work out on my own. There is no regimen I need to follow. There's no diet I need to follow. I just need to do some things for myself and that's it. And that will make me feel the happiest," the once-divorced star said. "No exercise is fun! I am going to dance around my bedroom and hopefully lose some weight -- and lift some weights and do what I can!"

Stephen Colletti Talks Kristin's Engagement

On Tuesday, the world learned that former Hills man-eater Kristin Cavallari is ready to settle down, after it was announced that the reality starlet became engaged to footballer Jay Cutler. During her time on both MTV's Laguna Beach and The Hills, the SoCal small-screen star fell in and out of love with Justin Bobby, Brody Jenner and Stephen Colletti, just to name a few.

And now one of those former paramours is offering his congratulations to the newly engaged actress. "I'm extremely happy for her," Colletti told Hollywood Life. "She deserves to be happy. She's getting engaged! It's weird. We're at that age now ... it's that reality check."

Colletti himself is currently dating Dancing With the Stars contestant Chelsea Kane, but he doesn't feel the need to put a ring on it just yet. "That's not something [that's on my mind right now]," he said. "Of course I'd like to get married someday though!"

Many of Cavallari's other former co-stars have remained mum on the subject, but former star of The City Whitney Port sent her love and support on Twitter. "@KristinCav heard from a little birdie the big news!" she wrote. "So happy for you, much love!!! Xoxo."

Cavallari has not directly commented on her engagement, but she did tweet her fans on Tuesday, writing, "My phone has not stopped today. Need to put it down."

Kristin & Jay: 5 Things to Know About Them

Kristin Cavallari and Jay Cutler are "very in love" and "so happy," a source tells PEOPLE, which stands to reason: Cutler popped the question over the weekend.

So what do we not know about the romance of the reality starlet and her NFL star fiancé?

1. They fell in love fast

They only began dating last fall, and their relationship has been primarily long-distance, but by January, Cavallari, 24, admitted Cutler already had her heart. "I'm in love and it's been great," she told PEOPLE. "Things are really good."

2. Cavallari has other ties to Chicago besides Cutler

"Chicago is great for me," Cavallari has told PEOPLE. "My mom and that whole side of the family is there … It's been nice to hang out with my mom." In fact, since the engagement, a source tells PEOPLE, Cavallari has been spending a lot of time out there.

3. Cutler has health problems, but they don't hurt his career

Noting he "had no energy," Cutler, who lost 35 lbs. in 2008, told the Associated Press that he'd been diagnosed with insulin-dependent diabetes. "It's a little overwhelming to get that news and realize you're going to have to completely change your life," he said, adding that the diagnosis is not expected to affect his play.

4. They share a love of charity

Among other philanthropic ventures she taken on, Cavallari has been involved in Until There's a Cure, a campaign to raise awareness and funds for AIDS and HIV.

Cutler does volunteer work for young people with developmental disabilities through Vanderbilt's Best Buddies program – and in 2007, he started the Jay Cutler Foundation, which partnered with Mile High United Way’s Youth Success Initiative to help at-risk youth overcome obstacles and graduate from high school.

5. They've both felt betrayed

Cutler, 27, was verbally attacked by some of his Chicago Bears teammates after the 2010 NFC Championship game against the Green Bay Packers for sitting part of it out due to a knee injury and appearing disinterested on the sidelines. Cutler later said the criticism "bothered" him.

Jessica Simpson Loves Being a Businesswoman

Jessica Simpson and fiance Eric Johnson were recently snapped at a slew of boutiques in London and Paris. A wedding dress hunt? Nope! Simpson -- Us Weekly's Style Icon of the Year, who heads her own wildly successful fashion line -- was "inspiration shopping for the collection," the superstar, 30, tells Us exclusively in the new issue. "I have the best job in the world!"

Simpson's labor of love has paid off: The Jessica Simpson brand has raked in $750 million in 35 countries!

And the singer, actress and reality star is completely hands-on with the creation of her chic but affordable line. "I'm in the workroom in [L.A.'s] Westwood a few times a week from 11 to 7 at night," she tells Us.

"Nothing goes out without me seeing it or my mom [Tina Simpson, cocreative director] seeing it," Simpson explains.

Working with Mama Tina, she says, is ideal -- and brutally honest! "We really know so much about each other and share so much," she says. "And we keep everything extremely truthful. If I walked in wearing something she didn't like, she would tell me. And I would tell her! Like, 'What the hell are you wearing?'"

Part of her current fashion success means a break from Simpson's Hollywood career, she admits. "This year, I've taken time for myself to enjoy being engaged and in love and being a businesswoman instead of an entertainer,"she says. "It's really helped the collection!"

About that engagement....

"I'm still trying to figure out what we're going to do about all of the plans," she says, adding that she be be "involved" in designing her gown.

"We have four dates floating around...It's going to end up being big!"

Jessica S: I'll Wear A Low-Cut Wedding Dress

Jessica Simpson may be a fashion mogul, but she's still at work on her most important look yet: her wedding dress.

"It's definitely going to be beautiful," the singer, who is engaged to former NFL player Eric Johnson, tells PEOPLE. "I want it to be different from what I've had before. I have a lot of tear sheets!"

Still, Simpson – who says she'd love to have a "Carrie Bradshaw moment" trying on lots of gowns – often gravitates toward v-neck or scoop necks, which flatter her physique and help her avoid looking "top heavy."

Besides, "I like my collar bone," adds Simpson, 30. "I have a long neck, so I like to show off my décolletage."

As for the color, "I haven't really thought about it," Simpson confesses. But, "I do like the romantic feel of a lighter color."

While she focuses on her dress, Simpson's bridesmaids will be busy choosing their own ensembles. "I definitely would want all my bridesmaids to be in everything different," says the bride-to-be. "Just [to reflect] what their personalities are.”

For now, though, with so many of the plans still up in the air, Simpson doesn't even know when the nuptials will take place – or where.

"It’ll definitely be somewhere warm!" she says. "Once I get what I want my dress to look like. We'll set a date."

Indeed, a family source tells Us that the blissful pair will likely wed. Trawick, after all, the source says, "was one of the only people who stuck by her through everything," including Spears' dark 2007 and early 2008 -- when she lost custody of her sons Sean, 5, and Jayden, 4, to ex Kevin Federline, and was briefly admitted to a psychiatric hospital.

"[Jason] was someone she felt she could be her true self with. [Marriage] is what they talk about and the direction they're going in," the insider says.

Whatever and whenever their nuptial plans, one thing is certain, Spears tells Us: "I've never been happier!"
