Bruno Mars feels his new song "Let It Rain" fits in with the new Twilight Saga movie perfectly.

The singer recorded the track for the penultimate installment of the vampire movie, Breaking Dawn: Part 1, and says the song pays tribute to the romance between lead characters Edward Cullen and Bella Swan.

"When I saw the scenes I was already working on a dark love song. In every relationship you don't want to lose your friend. That's the hardest part. I didn't want to write it like 'I'm gonna sink my teeth into you.' It was just honest, pure emotion."

As well as being pleased with the song, Bruno was also impressed with the movie as he experienced a variety of emotions: "I watched some parts that made me laugh. I watched some parts that made me bawl into tears and just cry and cry. I thought it was shot beautifully. They did some really cool stuff. The cinematography was great. And the storyline."
