Nikki Reed got Robert Pattinson on the soundtrack

The ‘Thirteen’ star - who plays his adopted sister Rosalie in the series - heard Rod strumming his guitar between takes on set and recorded him. After taking the demos to the production, they arranged for R-Patz to record two of his tracks ‘Never Think’ and ‘Let Me Sign’ for the movie’s soundtrack, which also included bands like Paramore, Muse and Linkin Park.
