By

As if starring in the hottest film franchise on the globe wasn't enough, another one of Nikki Reed's dreams recently came true when she and her husband, former American Idol contestant Paul McDonald, were chosen to record a duet for The Twilight Saga: Breaking Dawn - Part 2 soundtrack.

ET's Christina McLarty spoke exclusively with the actress/singer behind the scenes of the music video for All I've Ever Needed -- a song that Reed and McDonald penned themselves.

But just because Reed stars in the movie doesn't mean that she was given special treatment in the song-selection process.

"It's been like seven months now of crossing our fingers and praying that this happens," Nikki explained. "It was just, I think, two weeks ago that we got the phone call that it was real and that it was happening."

In the video, shots of Reed and McDonald at home are intercut with scenes of Edward and Bella's love story.

Reed described the video, saying, "It's just sort of the story of how it came about. It's us developing the song and creating it all and finding the different parts."

The Twilight Saga: Breaking Dawn - Part 2 hits theaters tomorrow, November 16.
