Seeing as almost everyone in Hollywood appears in the upcoming romcom New Year's Eve, the premiere at Grauman's Chinese Theatre last night packed almost as much star power as the Oscars!

Zac Efron, Josh Duhamel, Michelle Pfeiffer, Katherine Heigl, Sofia Vergara and Abigail Breslin came out to support their film, and a handful of other famous faces (including a very sparkly and possibly pregnant Fergie, Ryan Seacrest and Mark Salling) hit the red carpet as well. Fergs (and her bandmate) recently hinted that she was eager to start a family, so is it possible that she's got a bun in the oven?

And the Black Eyed Peas singer wasn't the only one to catch our attention on the red carpet! Ashton Kutcher posed for photos with Glee's Lea Michele, and we're not trying to start a hookup rumor here, but it seems like these two are quite cozy together. Wonder what Demi would say about this?!

Britney Spears hit the stage in Mexico City to perform her Femme Fatale concert for free. The 30-year-old pop star, wearing a slew of her sexy outfits, rocked the crowd at the Monument to the Revolution.

The mama of two Tweeted:

"I've had so much fun and received so much love from my fans all over the world while performing my Femme Fatale tour which I am grateful for. I want to return some of that love so I've decided to give my fans in Mexico a special night and perform my Femme Fatale show for free."

Just last Friday, Spears celebrated the big 3-0. Reportedly longtime beau Jason Trawick is close to popping the question. Put a ring on it already, J!

... and by essentials, we're talking hair product, cigarettes, lighter, Red Bull, her iPhone and water! A girl's gotta stay hydrated.

Lindsay Lohan, sporting wavy blonde locks under a fashionable hat, certainly has her hands full while leaving a West Hollywood hair salon.

Let's hope the one-time successful 25-year-old actress is able to juggle a busy career in the near future, too. We miss seeing Lilo on the big screen!

We're kind of lovin' her chic cowgirl look. Yeehaw!

It's been exactly one year since Ryan Reynolds and Scarlett Johansson announced their divorce, but the We Bought A Zoo star has no regrets.

In a recent interview with Cosmopolitan mag's January issue, the blonde beauty opens up on her two-year marriage to Reynolds, calling it "the best thing I ever did."

Johansson reveals:

"I'm a big believer that when something feels right, you should do it. I'm a big believer in instinct. Getting married was the right thing to do because it was natural. It grew out of a romance and love and a desire to have a future with somebody, and I was very fortunate that I married somebody who turned out to be the person I thought he would be."

The Avengers star adds,

"Relationships are complicated. Being married is a living, breathing process. I think I was not fully aware of the peaks and the valleys. I wasn't prepared to hunker down and do the work... Both of us were extremely busy. We spent so much time apart. It's very difficult."

But the newly single 27-year-old says she misses "having a partner and a confidant."

While ScarJo moved on with actor Sean Penn after the divorce -- the pair have since broken up -- Reynolds has been linked to former costars Sandra Bullock and Blake Lively.

It's been a very emotional year for Real Housewives of Beverly Hills star Taylor Armstrong, and now she's finally ready to release her painful untold story.

Taylor has just released the cover for her upcoming memoir, Hiding from Reality: My Story of Love, Loss and Finding the Courage Within, highlights the domestic abuse she suffered -- photos included -- at the hands of her late husband, Russell Armstrong.

The reality star tells People on the message of her first book:

"My book takes readers behind the glamour of Beverly Hills to show them the terrible violence I suffered, and the slow and painful process of rebuilding my shattered life. I want readers in abusive relationships to learn from my suffering and use my book to help them find their own courage within."

Armstrong filed from divorce from her late husband in July citing domestic abuse -- he tragically committed suicide just one month later.

The memoir hits shelves on Feb. 7.

Deciding to stay mum on Brooke Mueller's recent drug/assault arrest in Aspen Colorado last weekend, Denise Richards simply smiled as she shopped in Beverly Hills, on Monday.

The Wild Things star has publicly supported Mueller in the past, telling Extra in July, "I give Brooke a lot of credit. I know that she's struggling with her addiction and she wants to be the best mom she can be."

The celeb moms may share an ex-husband, Charlie Sheen, but Denise seems more interested in a quiet life raising her three daughters, while Brooke just can't seem to let go of her hard partying ways.

The troubled mother of two-year-old twins Max and Bob -- who were also in Aspen during the incident -- checked out of her most recent rehab effort in July.

Mueller was released from Pitkin County Jail for suspicion of assault and possession of cocaine with intent to distribute, after Sheen allegedly posted $11,000 bail on Sunday.

A hearing is set for Dec. 19.

Hot new couple alert!

He's newly single -- and has a soft sport for brunettes! -- but it was still shocking to see Ashton Kutcher get so cozy with costar Lea Michele on the red carpet, at the premiere of New Year's Eve in Hollywood, on Monday night.

The adorable pair actually do hook up in the upcoming film, and the Glee star was overjoyed that part of the job description included kissing Mr. Kutcher.

When the 25-year-old stunner, who looked gorgeous in a silver Valentino gown, was asked what's scarier -- kissing the Two and a Half Men star or singing in front of thousands, Michele told Entertainment Tonight: "I mean who wouldn't choose to kiss Ashton?"

New Year's Eve hits theaters December 9.

Spotted: Lindsay Lohan's little sis Ali (er, I guess it's Aliana now!) getting a jolt of caffeine at Coffee Bean before heading to a business meeting in West Hollywood.

Ali recently chatted with Page Six Magazine about her family and career aspirations, and not only did she shoot down the plastic surgery rumors, but she also told the reporter that she looks to Lindsay and their mom Dina for guidance. Interestingly enough, Ali made no mention of her weight (or lack thereof), but given the fact that she signed with Next Model Management back in August, it seems like she's on the right track! But is her scary skinny frame setting a bad example for other teenage girls who look up to her?
