Claire Danes shows off post-baby body at Golden Globes

And the winner of Best Post-Baby Body is … Claire Danes!

After giving birth to a baby boy just one month ago, the "Homeland" star looked stunningly svelte in a low-cut, red-hot Versace gown at the 2013 Golden Globes, which she tried on for the first time the night before.

"They did a miraculous job," she told E!'s Ryan Seacrest of the Versace team. "I've been in sweatpants for quite awhile, so this is exciting."

In the halter-style dress highlighting her slim waist, Danes looked "amazing," according to E!'s Kelly Osbourne.

The last time Danes walked the red carpet, it was at the Emmys in September, when she was six months pregnant. She walked away that night with the trophy for Best Actress in a Drama and since then, "Homeland" has exploded in popularity, racking up record ratings for its second season.

The third season, which Danes and the rest of the cast finished filming in late November, will premiere September 29.

Perhaps baby Cyrus will continue to be her good luck charm for the Golden Globes -- Danes revealed that he was with her parents upstairs at the Beverly Hilton.

"He'll be a month as of tomorrow," she said. "He's teeny teeny tiny."
