Amanda Seyfried posed on the red carpet on Sunday evening at the 85th Annual Academy Awards at the Dolby Theatre in Hollywood, and she may not be nominated for her role in Les Miserables, but she definitely caught our attention in this custom Alexander McQueen gown!

The 27-year-old actress also wore Roger Vivier shoes and a few small Lorraine Schwartz baubles, and she swept up her long locks in an updo and kept her makeup relatively simple.

Amanda will hit the stage during the ceremony to perform alongside her Les Mis cast, including Anne Hathaway and Hugh Jackman, who are nominated for Best Supporting Actress and Best Actor. Can't wait for that!

This looks like it's going to be a hit!

We've been given the first sneak peek of Lovelace, and we can already tell it's going to be racy! In the clip, Amanda Seyfried, who plays Linda Lovelace, chats with Larry Marchiano (played by Wes Bentley) as she takes part in a photoshoot.

Speaking about her sexual awakening, Amanda's character says, "At first I'm closed up like a flower bud and then gradually the petals start to open, and then I finally learn about myself and I learn how to enjoy sex. And I feel free."

The film is set to debut at the Sundance Film Festival and co-stars Sharon Stone, James Franco, Juno Temple, Wes Bentley and Chloe Sevigny. The Les Miserables star took over the leading role after Lindsay Lohan was dropped. Demi Moore was originally cast as Gloria Steinem, but was recently dropped from the movie as well.

We can't wait to see it!

Amanda Seyfried covers the new issue of InStyle wearing a gorgeous Chanel dress, and for her interview, the 27-year-old Les Miserables actress opens up about her relationships, her Dear John co-star Channing Tatum and she even reveals that she's on medication for OCD.

On dating actors, Amanda says, “The thing is, I can’t date anybody without it being portrayed as a serious relationship in the tabloids. It sucks! Like Josh Hartnett and I were friends; we hung out, we dated. I don’t actually have sex with every male I come into contact with … I’m just more attracted to actors. I like their choice to be artists—that’s ballsy. And a guy who has such access to his emotional life is sexy. Or maybe because lots of the actors I know are so broken. I don’t think I’m compatible with anybody I’ve dated. Maybe I’m so attracted to actors because I’m not ready for the “settled down” thing yet.” (Amanda's other famous exes include hotties Ryan Phillippe and Dominic Cooper ... not bad!)

So what does she have to say about Mr. Tatum? "Channing was amazing [to work with]. He’s a superstar. Everybody wants to have sex with him. And the only person he wants to have sex with is his wife, Jenna [Dewan]. He’s the most loyal husband.”

However, the interview gets a bit more serious when Amanda opens up about having obsessive compulsive disorder. “I’m too measured and controlling—about everything. That’s why I take Lexapro. It’s for OCD. I don’t feel like I’m struggling with it. I think OCD is a part of me that protects me. it’s also the part of me that I use in my job, in a positive way.” Good for her for speaking out about it!

Talk about star power on the red carpet!

Anne Hathaway, Amanda Seyfried and the always dashing Hugh Jackman looked picture perfect at the Les Miserables premiere at the Empire Cinema in Leicester Square, England.

While Anne looked stunning in a white Givenchy gown with pearl details, Amanda rocked a black ruffled Balenciaga dress.

As for Mr. Jackman, he looked beyond sexy in his Burberry suit. Such a handsome guy!

Is this her secret to scoring some of Hollywood's hottest hunks?!

Amanda Seyfried hit Equinox gym in Hollywood yesterday, and the In Time actress put her enviable physique on display in black spandex with a tight red top. Lookin' good girl!

We bet the blonde beauty is working out to look good for her new beau Desmond Harrington! It was recently revealed the Mean Girls star and the Dexter actor were dating after being introduced by mutual pal and Harrington's co-star Jennifer Carpenter. The new romance comes on the heels of the 26-year-old's break up with former flame Josh Hartnett and a brief fling with Lovelace co-star James Franco.

Life seems pretty tough for Miss Seyfried... not!

Amanda Seyfried has dated some of the hottest actors in Hollywood, but through it all, her darling pooch Finn will always be the No. 1 man in her life!

The Red Riding Hood star looked casual cool in skinny jeans, a black tank, sandals and her favorite Givenchy tote as she strolled through LA's Los Feliz neighborhood with her furry friend on Monday afternoon, just one day after she was spotted hanging out with Dexter star, Desmond Harrington.

Seyfried has most recently been linked to Josh Hartnett and her Lovelace costar James Franco, but considering the fact that she's such close friends with Jennifer Carpenter, it's likely she introduced the 26-year-old to her Dexter costar, and onscreen love interest.

With so many guys falling in line to date Miss Seyfried, should she really limit herself to just one?

Juggling coffee, car keys, breakfast and her black Givenchy handbag, Amanda Seyfried literally had her hands full while shopping in Hollywood, on Friday afternoon.

Although it was recently rumored that Seyfried had been trying to rekindle her romance with Mama Mia! costar Dominic Cooper, who she dated for two years, it seems the ex-couple have both officially moved on.

Cooper was spotted getting cosy with theater actress and fellow Londoner Ruth Negga in Ischia, Italy last week, and the couple actually met while he was still dating the Mean Girls star.

Meanwhile the 26-year-old blonde beauty has been enjoying a new romance of her own with one of Hollywood's hottest stars; James Franco! The pair met while filming the upcoming Lovelace biopic; Amanda plays the title role while Franco makes a cameo as Hugh Hefner.

It's not hard to see why Amanda Seyfried has such a flawless figure; she takes every opportunity to get active outside with her darling pet pooch Finn!

The Lovelace star looked fit and fabulous in spandex pants and a casual tee as she accompanied Dexter star Jennifer Carpenter and a pal on a hike in the Hollywood Hills, on Friday afternoon.

Despite the fact that Seyfriend is one of Hollywood's hottest starts, she's still totally down to earth and still makes sure to pick up after her dog. Love her!
