Cover Story: Jen's Baby Plan

In September 2005, just months after her split from then-husband Brad Pitt, Jennifer Aniston confessed to Vanity Fair her desire to have a child.

"There's an amazing man who's wandering the streets right now, who's the father of my children," she said. "In five years, I would hope to be married and have a kid...Maybe it's a fairytale, but I believe in happily ever after."

Three years since making that statement, Jen seems to have finally found her prince charming in a tall, dark and handsome younger man, nine years her junior to be exact, John Mayer.

"I've never seen Jen this happy — or this in love," a pal of the actress tells OK!. "Not since Brad."

Just three months into their relationship, the couple has jet-setted across the world, shacked up for cozy evenings together in her Beverly Hills home and even met each other's inner circles (John has gotten the thumbs up from Jen's BFF Courteney Cox and her husband David Arquette).

And, as of last week, the actress flew to Europe to accompany John, 30, on his European tour, where on June 28 witnesses spotted the two getting hot and heavy at La Famiglia restaurant in London. That same day, Jen was the proud girlfriend, taking photos of her man from the side of the stage while he performed in concert at the Hard Rock Calling Festival.

It's no wonder Jen wants to move fast. While she has a body and energy level most girls in their 20's would die for, not even she can fight time. Jen, who turns 40 on her next birthday, knows that now is her chance to have that long-wished for baby, and she wants to have it with John!

"It wouldn't be much of a surprise at all if they moved in together by the year's end," a friend of Jen's tells OK!. "And if they do, you can bet that there will be serious discussions about having children."
