Is Lindsay Lohan Dating a Guy?

Lindsay Lohan is secretly dating Entourage star Kevin Connolly, according to new U.S. reports.

Friends tell In Touch magazine the couple has been dating after "hooking up" at a party Leonardo DiCaprio threw at his Hollywood home last month.

A source tells the publication, "Lindsay and Kevin have been sneaking around. It's not serious yet, but they seem to have some sort of physical connection. Lindsay isn't sure what's going to happen, so for now she wants to keep things quiet."

Lohan was romantically linked to Scottish actor Gerard Butler after splitting up with longtime girlfriend Samantha Ronson earlier this year, and actor Connolly, who once dated socialite Nicky Hilton, was recently rumoured to be dating actress Hayden Panettiere.

The Heroes star denies the romance reports, stating, "I've known Kevin for so long. We're just friends."
