An old flame of "The Friends" actress Jennifer Aniston is selling a letter she wrote him 21 years ago.

According to Ananova, he is auctioning the letter on e-bay.

Aniston was just 15 and attending New York's High School of Performing Arts in the summer of 1984 when she and the man had a fling.

Along with the letter the man is also selling off a piece of paper on which Jennifer wrote her name and telephone number as well as a birthday message written on toilet paper from the man's house.

The man, who is keeping his anonymity referring to himself only as "Michael", has set a reserve of $100,000 on the memorabilia.

"Michael" and Aniston remained friends until 1991 when her career began to take off, reports the New York Post.
