SAG Award 2013: 'Homeland' Star Claire Danes Snaps Back Five Weeks After Giving Birth in Givenchy (Poll)

Claire Danes

Claire Danes, in Givenchy, is a double nominee for Homeland.

The sleep-deprived new mom, who gave birth to her son Dec. 17, was in super shape to accept her best actress trophy.

Claire Danes has made an astonishingly swift transformation from bump alert to baby-on-board to hot new mom.

Seeing her in a black one-shouldered Givenchy gown at the SAG Awards on Sunday night – after giving birth to her first child, Cyrus Michael Christopher, on Dec. 17 -- one has to applaud – and envy -- her glowing face and slim shape.

When she was just a few months pregnant, she wore an embellished J. Mendel white wrap gown to the the 2012 Met Gala.

A few months later, at the Emmy Awards -- pregnant but not showing much -- the Homeland star wore a draped silk canary yellow Lanvin Resort 2013 gown. Then she showed off her post-baby body at the 2013 Golden Globe Awards red carpet wearing a red hot Atelier Versace gown with a thigh-high slit and a sexy plunging neckline.

But the Givenchy design – with a dark crimson lip and a loose ponytail – put her squarely back on the designer’s must-dress list.

Even talking on the red carpet, she gushed more about her baby than her baby body.

"He's getting fat. It's very exciting," she told E! News' Giuliana Rancic on the red carpet. "All the time on the boob is starting to result in growth. He's getting rolls. He's starting to smile. He kind of knows that I exist. That's reassuring!"

During her acceptance speech at the Golden Globes, the actress thanked her cast and crew for being so accommodating on-set, especially the wardrobe department, who "had to pull on my pants every single day."

It's amazing that she looks so great after major sleep deprivation.

"I get some sleep, but I just think, like, 'OK, it's another 4 a.m. call, which I have a lot on set, working in film and television. So I'm sort of used to being sleep-deprived. But this is taking it to another level, and there isn't a weekend off. There's no break!”
