Nikki Reed and Paul McDonald have decided to end their marriage, PEOPLE has learned exclusively.
"After much consideration, Nikki Reed and Paul McDonald are ending their marriage. They have been living separately for the past six months due to work obligations," says a rep for the actress.
"They will continue to share their love of music, and are still working on their debut album, I'm Not Falling, releasing in 2014. They remain best friends and look forward to their continued journey together."
The Twilight star and the American Idol musician tied the knot in October 2011.
The actress, who has three films at this year's TriBeCa film festival, told PEOPLE last October about balancing marriage and working in Hollywood.
"It's important to communicate and stay on the same page," she said. "With what we do for a living, it's important we make each other know they come first."
