Aniston and Vaughn to marry?

Jennifer Aniston and Vince Vaughn are allegedly intending to marry in a secret ceremony.

Rumours have emerged that the Wedding Crashers star proposed to his actress girlfriend during a recent trip to Paris, and is already making efforts to get in shape so that he can look his best on the day.

Life & Style magazine reports that Aniston confided to a friend: "He's started the Zone diet and he's working out. He looks great."

The former Friends actress is apparently already making plans, despite wanting to wait until media coverage of the birth of her ex-husband Brad Pitt's first child has calmed down.

A source supposedly revealed: "Jen's already asked Courteney Cox to be her matron of honour."
