The magazine claims that Aniston ended things when she met up with a less-than-enthused Vaughn in London. The insider reveals, "Jen says she knew things wouldn't work out between them. They've tried taking breaks before, so this time she went one step further - and ended it!…their fighting was torture, and she'd had enough."

Spies for OK! magazine claim, however, that though it’s chilly between Jen and Vince, they are still a couple. And Jen has supposedly developed a plan to make Vince jealous - she’s been meeting up with her former “Friends� co-star Matthew Perry. OK! reports that Aniston and Perry have recently met up several times to go to a restaurant, walk on the beach or get ice cream. One source for the magazine says, “I definitely think [Jennifer] is trying to make [Vince] jealous by spending time with Matt. She has been very impatient with Vince not being able to make a real long-term commitment to her.�

Could Matt and Jennifer have long-term potential if things go sour with Vince? Could be. A source close to Jennifer says, “Matt was really supportive of Jennifer during her tough years after her marriage to Brad Pitt ended and he began seeing Angelina Jolie. This was a very tough time for her and Matt has been a rock throughout.� And those who saw the pals together insist they have chemistry. One witness to their beach stroll said, “Matt was walking with his arm around Jennifer’s shoulder. It was obvious they have a real fondness for each other.�
