Elizabeth Banks

When the biggest names in Hollywood, music and fashion get together, there are bound to be some friendly match-ups, and that's just what happened at today's Costume Institute Benefit. 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 favourite 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.

They say that Hollywood is a fickle place, and that couldn't be more true when it comes to stars and their hairstyles.

While most of celeb-land has been fairly quiet over the Christmas holidays (save for a baby announcement and some cool New Year's Eve celebrations), one place that's never silent is Twitter. While we've been taking a break, all our favourite celebrities have been as active on the social-media front as ever, tweeting well-wishes, funny thoughts, astute observations and anything else that comes to mind. Actress Lucy Hale takes issue with some modern technology features she doesn't appreciate, Andy Lee comes up with a uniquely Aussie new concept and Erin McNaught knows the solution to any problem . . . But that's not all — there's much more to read, so click through to check it out!

Reese Witherspoon, in a Miu Miu dress, was in the spotlight last night at the March of Dimes Celebration of Babies luncheon, where she was being honoured with the Grace Kelly Award for her commitment to healthy pregnancies and families. Reese had plenty of support at the event, which was hosted by Nick Cannon, including new mum Elizabeth Banks, and Hilary Duff and Mike Comrie. Megan Fox, who gave birth to son Noah in September, and her husband, Brian Austin Green, were inducted into the Stork Club for new celebrity parents and mingled with Molly Sims inside.

It was the first time Reese and Brian were at the same event since Brian jokingly thanked Reese for taking attention away from Noah's birth with the announcement of her own son, Tennessee. Amanda Peet broke from her small-screen role on The Good Wife to attend, and Alyson Hannigan was on hand as well. Reese got behind another good cause yesterday, when she posed at the Children's Defense Fund of California's annual Beat the Odds Awards. Both recent appearances came after a quick trip to NYC earlier this week.
