Neil Young and Daryl Hannah, who were recently spotted out showing some PDA, reportedly began seeing one another before Young filed for divorce from his wife Pegi Young.

The Neil Young, Daryl Hannah Affair

Young and Hannah have apparently been seeing one another for months, a source told People. Though Young may have only filed for divorce at the end of August, he and his wife had long been having problems.

"They've been dating for months," the 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.' "

"They've appeared at many, many protest rallies together over the past year," the insider said. "The fans have known about this for months."

Fans aren’t the only ones who’ve been wise to Young and Hannah’s relationship. David Crosby of the erstwhile Crosby, Stills, Nash and Young, seemed to reference the pairing – and his disapproval of it – in an interview earlier this week.

"I happen to know that [Young] is hanging out with somebody that's a purely poisonous predator now," Crosby told the Idaho Statesman. "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."

Neil and Pegi Young have been married for 36 years in which they’ve often collaborated on music and raised two children together. Their son Ben Young suffers from cerebral palsy, which led the couple to found The Bridge School. The singer filed for divorce from his wife on July 29.

Over a month after the divorce filing, Young and Hannah seemed to go public with their romance by dining out at a restaurant in Westlake, Calif., on Wednesday.

"[Hannah and Young were] holding hands and being really friendly, but they were not kissing or anything like that inside of the store," a source told People. "They were both very friendly to the employees, too. They both have been to Sur La Table many times before, but the employee has never seen them in the store together besides on Tuesday."

Neither Young nor Hannah have commented on the relationship or alleged affair.
