It's the battle of the Oscar winners!
Why? Mainly because even the Gravity actress admitted she's likely to lose.
"If Meryl and I get in a ring, she'll kick my ass," she told the The Short List. "People don't realize that there's a side of Meryl that's just mean. You walk away and she'll just rip your dress…I know not to turn my back on her."
And apparently the 64-year-old won't stop at wardrobe malfunctions. Sandra joked that she thinks the The Iron Lady star would do more than put a little hurting on her.
"I will try to kick her ass but she will kill me," she said. "That's just how it's gonna end and then she'll be lovely Meryl again and I'll just be dead."
We've seen The Devil Wears Prada so we don't doubt it.
But fear not fans this is all a part of the duo's long established faux public feud. We know that when the two really get together they are more likely to smooch than take a swing at each other.
"We will have a nice sparring I hope until the day we die," Sandra explained. "I love nothing more than hanging out with that woman and having a glass of wine."
Cheers to that!
