Jennifer Aniston Planning to Have John Mayer's Children?

Jennifer Aniston is planning to have a baby with John Mayer, a new report claims.

Despite recent claims the couple has split, Aniston has told "stunned" friends she is planning to have the 'No Such Thing' singer's children.

"Jen says she can talk to John about anything and a baby feels like a natural step," a source tells British magazine Look. "They're having a fantastic summer together and are hoping she'll be pregnant in the next few months.

"Jen could be feeling the pressure to become a mom because everyone in her close circle has kids. Courteney Cox, Sheryl Crow, and [Tobey Maguire's wife] Jennifer Mayer are three of her best friends and they're all moms, but friends are worried John won't commit and could leave Jen as a single mom if she has a baby with him."

Former 'Friends' star Jennifer, 39, is also rumored to have made a pledge to herself after her 2005 divorce from Brad Pitt to have a child by 2010.

The source adds, "Jen has always wanted a family. Seeing Brad with his four kids hasn't been easy for her.

"She wants a big family -- and with Brad and Angelina now expecting twins, it's made her all the more determined to be a mom."

Jennifer, who has dated a string of men since splitting from the 'Fight Club' actor, has also told friends she has found a "soul mate" in Mayer and is determined to get pregnant as soon as she can.

"Jen says John's definitely the right guy for her," the source adds, "and she already feels as if they've been together forever.

"She keeps saying she's finally getting what she always wanted."

The source continues, "Jen found her marriage collapse tough, but she promised herself she'd find true love, so she's delighted to have found John."

The pair, who have been dating a little over two months, recently went for lunch at Jennifer's close pal Courteney Cox's house; and Mayer got the thumbs up from Aniston's former 'Friends' co-star. "Jen has always followed her heart," the source adds. "Her inner circle always screen the men she lets into her life because they don't want her to end up heartbroken.

"Although concerned about her baby plans, Courteney likes John and has been saying he's 'charming, sensitive and hilarious', and her husband David Arquette has an off-the-wall sense of humor so the guys got on really well.

"Sheryl Crow already knows John and likes him too -- all her friends were shocked at her baby announcement but are praying that if she goes through with it, she will finally find happiness."
