'Jennifer Aniston Calling The Shots In John Mayer Romance'

Although Jennifer Aniston appears to have fallen for John Mayer in a big way, friends say it is the former Friends actress who is calling the shots in their blossoming romance.

Much has been made of Jen's eagerness to find love again after her divorce from Brad Pitt – and also of Mayer’s past form as a total player.

However, whilst she’s reportedly confided in friends that she’s besotted with the younger singer, the same pals insist that she’s taking things in her stride.

"This is a whole new Jen. She's trying new things, taking a risk, and is game for getting out of her shell, living her life and trying to be happy," OK! quotes one pal as saying.

A friend of John’s goes one step further by insisting that it is Jen who is calling all the shots when it comes to her new relationship – and it seems to be paying off!

The friend says, "She doesn't rush off and go on vacation with John, and she's made it clear she will not be a groupie at his shows."

"He was smitten with Jen and came to visit her on set. They're actually working around her schedule more than anything!"

Keep up the good work, Jen!
