Actress VIVICA A. FOX is at the centre of an alleged scandal - after reports of a sex tape featuring the star surfaced.

Atlanta blogger SandraRose claims Fox was filmed performing oral sex on an Atlanta man who secretly shot the sex act and emailed the footage to his friends.

It is claimed Fox has passed the tape on to local police, but it's unknown whether the alleged encounter is being investigated by the authorities.

On her blog, Rose writes, "In the tape, an apparently inebriated Vivica can be seen on her knees servicing a male friend who surreptitiously taped the encounter on his cell phone. Allegedly the man, who lives in Atlanta, emailed the tape to friends who emailed it to Vivica. She quickly forwarded the tape to a friend at the Atlanta police department. "It isn't known if Vivica filed an official complaint with the police or if she asked her police friend to handle the situation privately."
