Jennifer Aniston using Gerard Butler to keep John Mayer in line?
An inside source told OK magazine: “Gerard was laughing loudly towards the end of the meal while Jen was laughing uncontrollably!
“[They] have chemistry in spade and I wouldn’t be surprised if something clicked between them.”
But another source, claiming to be a friend of the former Friends star told the magazine: “Jen’s seeing John, but she let him know other men still find her attractive.
“[She] now has laid down some hard and fast rules for John, if he ever wants things to work out between them.”
