Parting was too painful for Avril Lavigne and Brody Jenner.

Despite their breakup earlier this month, the duo -- smiling brightly -- were spotted hitting the town together in West Hollywood on Monday night.

"They are not back together," source close to the "Complicated" singer, 27 and former Hills hunk, 26, explains to Us Weekly. The couple are still spending time together and "trying to figure out how to separate," the pal says.

Indeed, after two years together, the couple broke up amicably in early January as they struggled to balance their relationship with their careers.

 "It was mutual, but Brody really broke up with her," a source told Us. Jenner "started" the conversation as they were discussing singer Lavigne's upcoming tour dates in Asia. "He told her he was tired of always being her plus-one, and always going on tour with her."

"They still love each other and could get back together, but for now, he needed a break."
