Brad Pitt: "I Had to Keep Calming Myself Down," Says Costar

Find out what Angelina Jolie's main man is really like

Ya may not know who Jessica Chastain is right now, but you will soon.

The 29-year old actress has nine movies coming out in the next year so. Yes, nine!

Sure, one of them is Wilde Salome, an adaptation of Oscar Wilde's Salome written and directed by and costarring Al Pacino, but what really want to know about is the flick with...Brad Pitt!

So, here it goes...

Chastain plays Pitt's wife in Tree of Life, director Terrence Malick's film about a family with three sons in the 1950s, also starring Sean Penn. Chastain isn't allowed to reveal too much, but that doesn't stop her from talking about Mr. Pitt.

"I remember I was working and he came to set," she told me at Elle's Women in Hollywood event, where she was given the Calvin Klein Collection Emerging Star Spotlight Award. "I was like, OK, I'm going to meet Brad Pitt! I was trying to be like it's no big deal—we just have to play husband and wife!"

Turns out she had nothing to worry about. "He was so chill, nice and funny and cool," she said. "He's like a normal dude."

Even so, she did have to be careful. "I had to keep calming myself, like don't geek out," Chastain said. "Yes, this is Brad Pitt, but you have to be normal. At least I didn't scare him."

So did she get to lock lips with Angelina Jolie's main man? She smiled, "I can't tell you that."

Grrr.
