Did Ryan O'Neal Ever Hit Farrah Fawcett?

After Farrah Fawcett's passing in 2009, her longtime lover, Ryan O'Neal, is releasing a tell-all containing murky details about their tumultuous 30 years together -- a few of which he spilled to Chris Jacobs in a recent interview.

"There were moments that we'd bump into each other," O'Neal admitted when asked if their bouts ever turned physical. "Once I hit a door. She tried to close a door on me and I hit it, and I went through the door and the wood hit her in the eye." As a result, Fawcett allegedly sustained a black eye and O'Neal -- a broken hand.

The struggle to keep his relationship with Fawcett intact may have detracted from his job as a father. The couple's son, Redmond, once became so fed up with his parents' arguing that he put a knife to his chest, pleading with them to stop, which they did.

"They were difficult to raise," said O'Neal. "Redmond is in a rehab till October and he's sober. I have a great relationship with Patrick. Tatum is a work in progress, but Griffin is gone. Can't win 'em all."

In February, Griffin, 47, was sentenced to 16 months in prison after pleading guilty to two charges of driving under the influence and possession of a firearm by a felon.

O'Neal regrets never marrying Fawcett and claimed he tried to organize a small wedding at the last minute, but it was too late.

O'Neal said that he spent his last moments with Fawcett apologizing for "everything that went wrong."

Last month, O'Neal was diagnosed with stage 2 prostate cancer. Recently, he also had a melanoma removed from his nose.
