Jennifer Aniston Videos: I Think Pregnant: ET's Samantha Harris enjoyed some girl-talk with Jennifer Aniston, who opened up about motherhood and if she's ever considered going down the path of her character in 'The Switch' by looking into artificial insemination. "I want it to match my Jimmy Choos and my couch," Jen jokingly said about designing a baby. She tells Samantha in all seriousness, "I don't think for me personally that is something that I want, but again I say you don't rule anything out because I don't know what's going to happen anymore. I could walk out of this hotel and meet the man of my dreams or get hit by a bus. Anything is possible."

"For Kassie, it was almost like she was designing a Nike sneaker online," Jen said of her character. "I'm going to pick the perfect donor. He's going to be blonde; he'll have a high IQ."In 'The Switch,' her character Kassie was desperate to get pregnant and was on the hunt for the perfect sperm donor. That's when her best friend, played by Jason Bateman, accidentally swaps samples. Years later, he comes to the revelation that Kassie's child is possibly his biological son. "I will say it. This is his best performance yet," Jennifer tells ET of her real-life friend Jason.

Jason said of locking lips with Jenn, "It was a little weird to kiss her. ... Jenn and I just brought a lot of our friend history into this and therefore we really didn't have to work that hard."Jason related to the script because he is happily married in real life to his best friend Amanda Anka and the couple have a daughter who is turning four. After years of looking at her as only a friend, he evaluated his life and realized, "the only relationships that are lasting are my friendships, so in the interest of getting married once, let's marry a friend, somebody that I'm attracted to and preferably a woman."For comedy's sake, Jason joked, "You can't make [babies] with guys. I just learned that. I was trying and trying and trying. My guys were not getting pregnant."
