"They've been dating for months," a source told People. "They've taken no effort to even hide it. He recorded a new album a few weeks ago, and she was on Skype the entire time, giving him feedback on every take. He even told people in the studio she was his 'girlfriend.'"
Hannah is a passionate environmentalist and she apparently met Young while they were filming a documentary for Greenpeace about the Alberta Tar Sands.
"They've appeared at many, many protest rallies together over the past year," the source added. "The fans have known about this for months."
Young's former musical collaborator, David Crosby, spoke with the Idaho Statesman earlier this week and alluded to the fact that Hannah had been responsible for the end of Young's marriage.
"I happen to know that [Young] is hanging out with somebody that's a purely poisonous predator now," Crosby explained. "And that's karma. He's gonna get hurt. But I understand why it happened. I'm just sad about it. I'm always sad when I see love tossed in the gutter."
