The music mogul, who recently turned 50, revealed that he received the joke gifts from friends and family who think he is vain.
A friend of Cowell told the Daily Mirror that he said: "They came in all shapes and sizes - big ones, small ones, full-length ones, even dental ones so I can look at my teeth.
"A couple of people even bought me magnifying ones to help me inspect my wrinkles."
The source also said that the X Factor judge is planning to donate most of the mirrors to an auction to raise money for Battersea Dogs Home.
