Elizabeth Banks

When the biggest names in Hollywood, music, and fashion get together, there are bound to be some friendly matchups, and that's just what happened at 2013's Costume Institute Benefit on Monday. Stars mingled with their famous friends, walked the carpet with their designing pals, and brought their significant others to celebrate the Punk: Chaos to Couture exhibit at the Metropolitan Museum of Art. Go ahead and check out the fun duos at the Met Gala, including Jennifer Lawrence's Hunger Games reunion with Elizabeth Banks and Nicole Richie's run-in with Julianne Hough and Jaime King.

We have the third annual CinemaCon to thank for bringing together some of our favorite stars in one place: Las Vegas. Sandra Bullock, Elizabeth Banks, and Hailee Steinfeld are just three of the style-setters who made up this year's list of attendees — and we're looking to their dressed-up looks for serious cocktail-party inspiration. Without further ado, step inside to see who wore what at this year's CinemaCon.

Catching Fire is still filming at the moment, but for those too impatient to wait for the film's Nov. 22 release, we've got a little treat. Behold, lovely character portraits featuring the stars of the Hunger Games sequel. Katniss, Effie, Haymitch, Caesar, Peeta, Gale, Johanna, Beetee, and Cinna have all gotten the royal treatment, and we'll be seeing more of the cast in the next few days. Check out the newly released portraits, and let us know what you think!

Happy birthday, Elizabeth Banks! On Feb. 10, the actress, producer, and director turns 39. Not only does Elizabeth Banks juggle a variety of jobs in Hollywood, she also plays a variety of characters — both funny and serious, TV and film. In last year's People Like Us, she stepped into the shoes of a single mom and bartender who builds a relationship with a man she doesn't know is actually her brother. She also tackled complicated sibling relationships in 2011's Our Idiot Brother, in which she played one of three sisters having to deal with their troublesome brother and his effect on their love lives. Whether she's playing a sloppy kisser at a Summer camp in the '80s or a strong-willed, workaholic CNBC news anchor, Elizabeth's notable TV and film characters always know what they want and how to go after it. So from the lips of Elizabeth Banks's characters, here's how to be a confident woman in your familial and romantic relationships.

Celebrities kicked off February by getting to work on set this week. Elizabeth Banks and James Marsden seemed to be having fun filming Walk of Shame in West Hollywood, while Tom Cruise and Emily Blunt were smiling on the set of their new movie All You Need Is Kill in London. In NYC, AnnaSophia Robb filmed scenes for The Carrie Diaries, and Jennifer Hudson hailed a cab on the set of Black Nativity. Click through to see all of this week's stars on set!

A busy award season hasn't slowed down the Hollywood stars who spent this week hard at work on set. In NYC, Jennifer Connelly spent a day working on Winter's Tale with her daughter, Agnes Lark Bettany, by her side, while Colin Farrell took center stage on the same set later in the week. In LA, Elizabeth Banks brightened up the set of Walk of Shame in an all-yellow ensemble, and things got intensely funny on the set of New Girl in a scene with Zooey Deschanel, Max Greenfield, and Jake Johnson.

Elizabeth Banks slipped into a sexy yellow dress to film scenes for Walk of Shame in LA yesterday. The movie follows Elizabeth's character's journey across LA after a one-night stand. During her latest day of shooting, she ran around on set in heels and covered up in a warm jacket in between takes. Elizabeth has moved on to the comedy now that she's wrapped work on Catching Fire. Some of the production on the Hunger Games sequel took place in Hawaii last year, and we've already gotten a sneak peek at pictures from Catching Fire.

Elizabeth, who has two sons, may be in the spotlight for her acting, but she's also in the headlines for her recent statements about parents with only one child. Elizabeth told People, "You don't realize how easy one is until you have two. Now I'm really a mom. Oh, I am a mom now! This is for serious — I am responsible for two people now."
