Muse singer Matt Bellamy has revealed that their contribution to the Twilight Saga: Eclipse soundtrack is about his split from his girlfriend.

‘Neutron Star Collision (Love Is Forever)’ is the lead single to the score, which is released on June 8.

Bellamy said he had written the song straight after breaking up with his girlfriend last year, and that it was about the moment two lovers meet for the first time.

"It was a song looking right back on that moment that you first get with someone and everything feels like its going to go on forever,” he said.

Speaking on BBC Radio 1, Bellamy continued: "The Twilight people contacted us and were very keen to get a song for their film and I thought 'Why not?'

"I might as well just bung it in there and get it out there because this song represents a bit of a difficult period for me in my life.”

The singer added that the track was "kind of like a cheesy love sentiment".

The soundtrack to The Twilight Saga: Eclipse also features songs by Florence & The Machine, Beck, Bat For Lashes and The Dead Weather.

The film stars Robert Pattinson and Kristen Stewart, and is released on June 30.
