It's been less than a month since Claire Danes gave birth to her first baby -- and boy did she bounce back quickly!

The "Homeland" star and nominee hit the red carpet at the Golden Globe Awards tonight in Los Angeles looking skinnier than ever in a tight red Versace gown.

The actress, 33, and husband Hugh Dancy, 37, welcomed son Cyrus Michael Christopher Dancy on Monday, Dec. 17.

Of course, Danes barely showed off a belly when she accepted the Emmy Award back in September (left), so maybe she didn't have too much to lose. Lucky!
