Perry cashing in on the problems between Jennifer Aniston and Vince Vaughn.

It’s not looking good for Jennifer Aniston and Vince Vaughn. They have not been photographed together in some time and many gossips are suspecting that they may have split. Prolonged separation seems to be at fault, as Vaughn has been filming a movie in London over the last few weeks.

A friend of Aniston’s told Life & Style Weekly, "Jen and Vince had been fighting over the phone since he started traveling. She said it was making both of them miserable." The pal claims that the tension between Jen and Vince only increased when the actress tried to have a conversation about their relationship. "Vince acted distracted and closed off and refused to discuss their future," says the source.

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.�
