John Stamos (above).

John Stamos’ lawyers denied today that Stamos had an affair with 17 year old Alison Coss in 2004, who is on trial along with Scott Sippola for attempting to extort $680,000 from the actor so that they would not release pictures of Stamos partying with strippers and cocaine.

In opening statements, defense lawyer Sarah Henderson claimed Stamos and Coss had a romantic fling when she was just 17.

Stamos’ lawyer issued a statement denying it. On the stand, Stamos described his encounter with Coss as “just hanging out” and “socializing” with her and others in a hotel.

He said he and Coss continued a “flirty,” but “friendly” e-mail exchange afterwards.

“It was all very sweet. I considered her a friend,” he said.

That’s a far cry from scene described by Henderson, who said Stamos and Coss kissed and had a partially nude romp in a hot tub before he offered to perform oral sex on her – which she declined.

In Florida, it is a second-degree felony for someone older than 24 to perform oral sex on anyone 17-years-old or younger.

We’ll keep an eye on this for you.
