The 27-year-old 'Mean Girls' star was allegedly fooling around with her girlfriends when she jotted down the names at the Beverly Hills Hotel on January 30 last year and later tossed the paper aside, reported In Touch magazine.
Lohan named 36 of her famous lovers but only some have been revealed as the blurred ones are censored for "legal reasons."
Some of the names were either married or in a relationship and the list "could rock several Hollywood relationships to the core."
"They were giggling and talking about people in the industry. It was her personal conquest list. She was trying to impress her friends with the list and then tossed it aside," a source said.
So far only Hedlund's representative has come forward with strong denial. Lohan and Hedlund were co-stars in 2001 film 'Georgia Rule'.
