Lindsay Lohan has trashed reports claiming she is romancing model Adam Senn.

The Mean Girls actress has been linked to a string of rumoured beaus since her split from DJ girlfriend Samantha Ronson earlier this year, including Jason Segel, Entourage star Kevin Connolly, and Gerard Butler.

The 23-year-old star slammed reports of a new man in her life by declaring on her Twitter page that she was single.

“I”m not dating my friend, people are nutso (sic), and it’’s not a way to start off the new year with rumours,” the Daily Express quoted her as saying on the popular microblogging website.
