Ryan O'Neal has blasted explosive new allegations he began a love affair with Farrah Fawcett's best friend Alana Stewart as his longterm girlfriend fought for her life.
The veteran actor's estranged son Griffin is one of a number of sources to come forward with the sordid claims, accusing O'Neal of having an inappropriate relationship with Stewart.
O'Neal and Stewart have grown closer in the last three years after rallying together to support the Charlie's Angels star as she bravely battled anal cancer.
But Griffin O'Neal claims their friendship took a romantic turn in Fawcett's final months, before her death on 25 June.
He tells In Touch Weekly magazine, "They were sharing a room together."
The 44 year old goes on to claim Fawcett's ageing father, Jim, once walked in on the pair in the bedroom after flying in from Houston, Texas to visit his ailing daughter.
Griffin adds, "It made Jim uncomfortable, so he packed his bags and went home."
His allegations have been backed up by Javier Salazar, a friend of O'Neal and Fawcett's son Redmond, who admits, "Ryan and Alana's relationship was fishy."
A former business partner of Fawcett's goes on to add, "Ryan and Alana are a little too cozy with each other. It is raising eyebrows. They both stayed at Farrah's (home) in the end."
Representatives for both O'Neal and Stewart have denied the salacious claims to In Touch, but have declined to comment further.
