She may have planned "almost nothing" for her nuptials to Justin Timberlake, but Jessica Biel definitely channeled a bride-to-be at the Total Recall premiere in NYC, wearing a lacy white Elie Saab dress, Jimmy Choo shoes and her dazzling $130K diamond engagement ring, on Thursday evening.

Not to be outdone by her gorgeous costar, Vivica A. Fox looked stunning in a sexy leapord-print dress with sparkly sleeves and oversized silver and canary diamond earrings.

Before stepping out on the red carpet for the premiere, Jess made an appearance on The Daily Show earlier in the the afternoon, wearing a glamourous Giambattista Valli dress, paired with H. Stern jewels, and she donned a powder pink Dior Couture gown for the film's Hollywood premiere the pervious night.

Which of Biel's Total Recall looks is your fave?

Ah, it all makes sense now ... especially after last night's cotton candy pink 1990s prom dress!

Jessica Biel is busy promoting Total Recall (today she stopped by The Daily Show With Jon Stewart in NYC), and the 30-year-old actress revealed that she counts on fiance Justin Timberlake for tips when it comes to her wardrobe.

Jess told The Sun, "We both really love fashion. There are definitely moments where I'll come out in an outfit and he'll give me that look! He'll take me back into the closet and I'll change my shoes and I'm like, 'Yeah, this is way better.'" However, she doesn't always agree with his suggestions. She added, "Sometimes I won't change!" Hmm, so maybe she should be listening to him? We'd love to know when he's the one calling the shots on her outfits!

Looks like the ladies of Total Recall are giving us a lot to think about when it comes to fashion.

While attending the movie's premiere at the Grauman's Chinese Theatre in Hollywood, both Jessica Biel and Kate Beckinsale chose two very different looks.

While we appreciate Biel's choice of color, the gown is a bit prom-ish to us ... but that engagement ring from Justin Timberlake is to die for.

As for Beckinsale, the reptilian gown is a bit extreme, but for a movie like Total Recall, it's the perfect fit!

Jessica Biel and Justin Timberlake aren't ready to walk down the aisle just yet!

The bride-to-be got engaged to the pop superstar last Christmas, after he proposed with a $130K ring, but she's still enjoying her engagement and isn't about to rush into the wedding planning process.

Biel told the Chicago Sun-Times on Tuesday that she's planned "almost nothing" for the big day, revealing: "I'm just enjoying being engaged. I do feel like there is a lot of time and nothing needs to be rushed."

The couple have been dating for five years, but the Total Recall star admits:

"Everyone tells me that being engaged is the really special moment. Not that it gets bad when you get married! But being engaged is just absolutely amazing. You're in this romantic, ahhhhh, breathless moment that I'm just trying to extend as long as possible."

Kate Beckinsale and Jessica Biel promoted Total Recall at Comic-Con 2012 in San Diego yesterday, and the ladies revealed that neither one of them ended up with the part they originally auditioned for. Beckinsale plays Lori (co-star Colin Farrell's onscreen wife) and Biel plays Melina, the woman who helps Farrell's character after he goes through the "Rekall" experience.

Biel told MTV that she tried out "like three different times," first for Lori then for Melina and then for Lori, adding that she was the one who pretty much decided which role she was going to take. "[I] read with Colin for Lori, wild enough, and then [director Len Wiseman] and I just talked about it," she said. "I sat by myself for a while and thought, 'You know what? I want to be the heartbeat of this movie. I want to be that person who's with Colin, going through it, getting involved in it."

So what about Kate? "When my husband [Wiseman] first signed on to the project, he was like, 'Oh my god, I really want you to play this b*tch-psycho wife.' I was totally offended and didn't think any more of it for a while," she admitted. "I suddenly got a call, not from my husband, but from the head of Sony saying, 'Will you play Lori?' I thought it was a joke because I thought at least my husband was going to give me a heads-up ... so that was wild."

Speaking of wild, Wiseman reportedly had a very different role in mind for his wife. "We'd had a conversation about the fact that I wasn't available and we were both being very grown-up about it and he said, 'Well, maybe, will you play the three-breasted hooker just so that you're in the movie?' And I was like, 'OK,' because it had been a very long time since I saw the movie," she said. "I'm so glad that I didn't do that. I mean, she gets more attention than Jessica or me put together," Beckinsale said. "My daughter would die. She'd be so mad at me, going into eighth grade, if I was walking around with three boobs all the time. She'd be really annoyed."

Jessica Biel and Justin Timberlake are one step closer to taking the plunge!

The sexy pair threw an A-list engagement party on Saturday at the California home of Timberlake's longtime friend, Estee Stanley, and it was catered by Wolfgang Puck.

The dress code was cocktail attire and Timberlake donned a black suit and a fedora, while his bride-to-be wore a leopard-print halter dress cinched at the waist with a hot pink belt and matching shoes, according to US Weekly.

The 100-person guest list included Lance Bass, JC Chasez, Trace Ayala, Ellen DeGeneres, Portia DeRossi and Amy Adams.

An insider revealed to US:

"Jessica and Justin were mingling both separately and together throughout the party. Jessica seems to be very close with Justin's friends and vice versa. You can see that they have been dating for a long time and really know each others friends and family well. The party was a fun celebration and a preview of what's to come with the wedding."

He plays a villain in the film, but James D'Arcy was all smiles as he chatted up costar Jessica Biel on the set of the upcoming flick, Alfred Hitchcock and the Making of Psycho in Hollywood, on Tuesday afternoon.

The newly engaged star looked retro-chic in a 1960's inspired dress for her role as Vera Miles, who played Janet Leigh's sister in the flick. Scarlett Johansson will reenact Leigh's infamous shower scene, while D'Arcy has been cast as Anthony Perkins, aka the creepy motel owner, Norman Bates.

In other news, Jessica's finace, Justin Timberlake, is gearing up to compose the original soundtrack for her next flick, The Devil and the Deep Blue Sea. We can't wait for the hot couple's summer nuptials!

Jessica Biel really has that 60s look!

The newly engaged actress took a step back in time as she donned a long tight skirt, sexy red blouse and a vintage up-do to play Vera Miles, the actress who played Lila Crane for the upcoming film, Alfred Hitchcock and the Making of Psycho, on Saturday afternoon.

But our fave part about Biel's outfit was her $35,000 Row backpack, which she got as a gift from Ashley Olsen, lucky girl!

Justin Timberlake's wife-to-be, who joined Twitter last week, shared: "In love with my new #therow backpack. Thanks, Ashley."

Oscar winner Helen Mirren was also on the LA set alongside Biel, wearing a less-than flattering costume for her role as Alma Rainville, Hitchcock's wife.
