Dr. Paul Nassif -- I Did NOT Do This to Adrienne

Dr. Paul Nassif's lawyer tells TMZ, his client absolutely, positively did NOT inflict the bruises and marks depicted in disturbing photos released by Adrienne Maloof's personal chef.

Adrienne's chef Bernie Guzman -- who has appeared on several episodes of "Real Housewives of Beverly Hills" -- just posted the eight photos on his Facebook page, strongly insinuating Paul is responsible for the injuries.

Bernie wrote several messages on his wall as he posted the photos, saying, "ADRIENNE MALOOF WAS PUSHED TO THE GROUND. PUNCHED & BEATEN ... HE IS A BEAST."

Bernie goes on: "THIS IS ABOUT SAVING THE LIFE. OF A MOTHER AND HER CHILDREN ... EVERYONE NEEDS TO SEE THESE PICTURES ... NOW!"

Dr. Nassif's lawyer, Marty Singer, tells TMZ, "Any suggestion that the photos show my client struck Adrienne Maloof is a complete fabrication." Singer goes on, "No physical assault ever occurred."
