It looks as though Courteney Cox might be pressuring her friend Jennifer Aniston to get pregnant before she walks down the aisle this summer. According to reports, Aniston is so "fed up" with Cox constantly talking about pregnancy and babies that she is thinking about making her pal Chelsea Handler her Maid of Honor instead of Cox.

Jennifer Aniston Justin Theroux Pregnancy Rumors: Jennifer Reveals Details In New Interview

A source tells Radar Online: "Courteney has been pushing Jen to get pregnant for years! She's given Jen non-stop baby and pregnancy advice, and Jen is sick of it. She doesn't want a friend who's a total know it all. She'd much prefer to spend her time with someone like Chelsea, who would never tell her what she should or shouldn't do."

As far as Cox and Handler though, it seems as though there is friction between Aniston's group of friends as Cox isn't a fan of Handler's loud and centered ways.

"Courteney can't stand Chelsea. Courteney thinks she is loud and crass -- while Jen thinks Courteney is taking things too seriously and is acting like a jealous teenager," the source added. "It's gotten to the point where neither of them wants to make the effort to keep their friendship going."
