LOS ANGELES: Alana Stewart has slammed allegations she embarked on a love affair with best friend Farrah Fawcett's longterm partner Ryan O'neal - branding the reports "despicable".

The veteran actor's estranged son Griffin recently accused O'Neal of having an inappropriate relationship with Stewart as Fawcett fought for her life.

Ryan O'Neal and Stewart grew closer 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 (09).

He told In Touch Weekly magazine, "They were sharing a room together."

His allegations were backed up by Javier Salazar, a friend of O'Neal and Fawcett's son Redmond, who said, "Ryan and Alana's relationship was fishy."

Representatives for both O'Neal and Stewart were swift to deny the salacious claims - and now Stewart has taken aim at the people behind them.

She tells website GossipCop.com, “It never happened. Saying that is despicable.

"It's inconceivable anyone would say that. I would never do anything before, during or after Farrah's death. I was a friend of Farrah's for 30 years."

Stewart has also blasted Griffin O'Neal's claim that his father "was using Farrah for her money and fame", insisting that Ryan O'Neal "has never taken a dime from (Fawcett)" and had "always been generous to her".

She adds, "Ryan has plenty of his own money, more money than Farrah did."

Despite her anger over the allegations, the 64 year old has decided not to take legal action against O'Neal's estranged son: "There’s no point in suing Griffin, because it would cost tens of thousands of dollars in legal fees."
