Jennifer Aniston wants a baby with 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 and enjoyed cozy evenings together

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."
