The couple began dating in June 2005 during the making of hit comedy The Break-Up, and despite refusing to go public with their relationship, it was alleged the pair were planning to wed.
However, there have been rumors in recent weeks that their relationship was cooling off. Vaughn, 36, has been filming Fred Claus in London since late September, while Aniston, 37, has been busy filming in Los Angeles and New York City.
In October, Vaughn threatened to sue several tabloid newspapers after it was alleged he was seen kissing a mystery blonde in the British capital.
The pair's representatives, Stephen Huvane and John Pisani, told People magazine, "After Jennifer's trip to London several weeks ago, Jennifer and Vince mutually agreed to end their relationship, but continue to be good friends today."
