The 'Thor: The Dark World' star and the 'Twilight' actor have chosen to end their relationship after three years, citing "conflicting family and work commitments on opposite coasts".

A statement released on behalf of the pair reads: "Due to conflicting family and work commitments on opposite coasts, and after much consideration, Peter and Jaimie have chosen to part ways amicable and remain good friends."

The news will come as a surprise to fans as they were only recently discussing having a "stunt-oriented" wedding.

She said at the time: "We're just moving slow because both of us are so busy. But we're toying with the idea of doing something kind of stunt-oriented to just mix it up and doing something kind of wild and fun.

"But if I could have someone else do it [put on a white dress] for me I'd be, like 'Great'. I just don't have it in me, that, like, girly gene that's, like, 'I need to be in a white dress.' I could be in a pair of jeans and be just as well."

Peter got down on one knee to propose to Jaimie on top of the Empire State Building in New York in March 2015.
