Minnie Driver's baby landed her a role in new film 'Motherhood'.

When Uma Thurman found out that Minnie was pregnant she immediately got her cast in the movie alongside her.

Minnie - who is seven months pregnant with her first child - plays a pregnant woman in the film, and didn't have to rely on pillows to enhance her baby bump.

After being cast in the movie, Minnie admitted she was terrified about working with "beautiful" Uma.

She said: "I'm going to make a film with Uma Thurman, who I've never even met and I'm fairly intimidated by the idea of making a film with this gorgeous woman.

"I'm really hoping that my waters don't break on her shoes or something in the middle of a scene."

The 38-year-old actress has so far refused to reveal the father's identity, but has previously hinted he is English and "sort of in the same business".

Speaking of her pregnancy last month, she said: "This was an unplanned pregnancy, it's been very happily received by everyone, which is great. It's something I've wanted to do my whole life. I can't believe I've waited this long."

Minnie's sister Kate is also pregnant, by 'The Chronicles of Narnia: Prince Caspian' producer Matthew Stillman.

Romantic comedy 'Motherhood', which also stars former 'ER' actor Anthony Edwards, is being filmed now, and will be released in 2009.
