Taylor Lautner and Marie Avgeropoulos has broken up.

The 'Twilight' actor and his 'Tracers' co-star - who met in the summer of 2013 - are said to have ended their relationship a few month ago and remained friends.

While the pair are yet to confirm the split, a source told E! News: ''It was completely amicable. Taylor is dating and having fun. Nothing serious.''

It isn't the first time Taylor, 22, has dated one of his co-stars.

He was also romantically linked to Lily Collins after they starred together in the 2011 thriller 'Abduction' and popstar Taylor Swift after filming 'Valentine's Day'.

No reason has been given for the latest split.

The hunky star previously claimed he is a very ''loyal'' partner and thinks ''honesty'' is the most important thing when trying to make a relationship work.

He said: ''Honestly and loyalty are key. If two people can be honest with each other about everything, that's probably the biggest key to success. I like to think of myself as very loyal, and I love everyone I surround myself with, whether they're friends or girlfriends or whatever. I love loyal people.''
