According to Jessica Chastain, Cate Blanchett sent her into a fit of giggles at this year's Golden Globe Awards when the latter actress shared something "a tad naughty" on the red carpet. So what did the "Blue Jasmine" star tell her? Blanchett, for one, isn't saying.

"No comment," said the actress when prodded backstage at the SAG Awards on Saturday. "See, I don't participate really in social media, so that was extremely funny and naughty and private."

What Blanchett was willing to share, of course, was her elation at winning the SAG Award for Outstanding Female Actor in a Leading Role at the ceremony for her performance in Woody Allen's "Blue Jasmine."

"This has been an extraordinary, extraordinary, unexpected week," she gushed. "My husband arrived this morning, and I met [Lifetime Achievement Award recipient] Rita Moreno, and now this. And Robert De Niro gave it to me. So I mean, it doesn't get much better than that really."
