Shailene Woodley and Aaron Rodgers call off their engagement

Shailene Woodley and Aaron Rodgers have called off their engagement, a source close to Woodley told CNN.

"They grew apart, both have busy careers and unfortunately their relationship took a backseat. There is no animosity and they will remain friends," the source said.

Their respective representatives have not responded to CNN's request for comment.

Their break up comes nearly one year after Woodley's interview with Jimmy Fallon in which she confirmed that she was planning to wed the football star.

"Yes, we are engaged," Woodley said. "We are engaged. But for us, it's not new news, you know, so it's kind of funny. Everybody right now is freaking out over it and we're like, 'Yeah, we've been engaged for a while.'"
