PAMELA Anderson signed autographs and posed for photos with students after addressing the Oxford Union about vegetarianism yesterday.

The Baywatch star spoke to about 200 students and introduced documentary Glass Walls, narrated by Sir Paul McCartney.

The 43-year-old former Playboy model said she took up the cause after seeing her father hunt. She then persuaded him and his friends to give up the sport.

She spoke on behalf of People for the Ethical Treatment of Animals (Peta).

After the talk she spent half-an-hour answering students’ questions.

Omar Asfar, a 19-year-old Regent’s College student, said: “She sounded committed to what she believed in.

“She was looking well and afterwards she was very happy to sign leaflets and pose for photos.”
