golden globes hollywood hbo red carpet These three sure did have a lot to smile about last night!

Girls creator and actress Lena Dunham and her co-stars Allison Williams and Zosia Mamet took home the award for Best TV Comedy at the Golden Globes last night, and what better way to celebrate such a huge acheivement than by sipping champagne and rubbing elbows with Hollywood's hottest stars at the network afterparty?

Not only did Miss Dunham's show get recognized, but the quirky star also took home the award for Best Actress for her role as Hannah on the hit HBO series, which premiered its second season last night.

Other attendees at the soiree included James Van Der Beek and his wife Kimberly Brook, Olivia Munn, Dev Patel, Bill and Giuliana Rancic, Hayden Panettiere, Julianne Moore and others.

What a magical evening!
