Jennifer Aniston Gets Artificial Insemination

On the Big Screen! Jennifer Aniston has signed on to play a woman who wants to get pregnant via artificial insemination, Variety reports.

In The Baster, the actress and Juno's Jason Bateman star as best friends. After Aniston's character admits her fertility plans, Bateman's character -- described as neurotic and insecure -- secretly replaces the donor's sperm with his own, but then has to live with the secret that he's the child's real dad.

The flick, which begins filming this spring, is based on a short story of the same name that first appeared in The New Yorker. The currently childless Aniston -- who turns 40 on Sunday -- has declared that she'll have kids one day. "I just know it," she told Vogue last year.

In other recent news John Mayer appeared on Monday's Ellen DeGeneres show and talked about girlfriend Jennifer Aniston's new high-tech house -- and admits he occasionally sleeps over.

"There is no normal thing in the Aniston house," he says. "You won't find a light switch. The light switch is not antiquated."There is a six-button light panel. It does everything," Mayer goes on. "The top button is on and the button right below that one seems to be an air horn, so in the middle of the night, it [can be] very difficult [to sleep]."

Aniston gets confused by her high-tech home, too.Says Mayer, "The other day, I'm like, 'This is the most beautiful kitchen of all time. Where is the trash?'" Aniston, he adds, "didn't know where the trash was.

DeGeneres then puts Mayer on the hot seat, asking him if he sleeps over."Yeah, there are sleepovers, yeah," he says. "Yes, yes, there are."

Mayer also opens up about that infamous photo of him wearing a Borat-esque, one-piece bathing suit on his cruise."It is not photo-shopped," he says of the photo. "I sort of get drawn into the vortex when I look at it for too long.

"I have this cruise ... and the thing about a cruise is, everybody is supposed to let their hair down a little bit," he goes on. "I let a lot of hair down, but the fact is, that is something you're supposed to do for your fans. It's just plain silly."

Meanwhile, Aniston was on the DeGeneres' show Friday and admitted she isn't nervous about turning 40 on Feb. 11.

"I have to say, really, I feel better than I ever felt in my life," she said. "I did have a moment, though, over the weekend... I found a really long gray hair, and it kind of flipped me out.

"It's not my first, but it's the fact that it was so long," she said. "I was like ... 'How many others are there and what does that mean?' It actually brought me to tears, slightly.

DeGeneres then asked who will be going to Aniston's birthday party Saturday. Aniston said definitely her BFF Courteney Cox.

When DeGeneres held up a photo of Mayer (in a one-piece bathing suit), Aniston said, "I got to tell you, honestly, I almost don't want to touch it."

DeGeneres then commented on Mayer's swimsuit, and Aniston said, "The man’s got balls - what can I say?
"I think he's funny," she said, before adding, "let’s put [the photo] down now."
