farrah fawcett's possible secret love life revealed. It's all over involved in a lawsuit over a $30 million portrait of the actress. Reporter: This morning, a love triangle, involving ryan o'neill, farrah fawcett, and her college sweetheart, greg lott. We were in a consensual relationship. No other girlfriends or boyfriends. Reporter: These two men in this youtube video continue feuding, each claiming to be the love of her life. Don't get hostile with me. You weren't in her life. I wasn't in her life? We have a son. Reporter: The alleged 11-gyro manse between lott and fawcett came to light in a deposition, during a lawsuit between o'neill and the university of texas, over this portrait. Lott is expected to testify that it was fawcett's wish to bequeath all of her artwork to the university of texas. But o'neill claims, before she tied, she gave one of the paintings, estimated to be worth $30 million, to him. He's a coward and a liar. Reporter: Lott says they first dated for two years at the university of texas, and reconnected decades later. As proof of his claim, he has provided years of phone records and handwritten love notes between them. In one of them, she writes, great food, great weather, great sex, great, great you. I think it's despicable the way he treated me. He kept me from seeing the love of my life before she died. Reporter: But pictures and video show fawcett with o'neill over the years. Right up to her death.

Farrah did leave lott $100,000 in her trust, and nothing for o'neill. The testimony is going to be interesting, to say the least. This one not over by a long
