Lindsay Lohan 'spending every night with different man'

Lindsay Lohan has been spending time with 'a different man every night' following her break-up with Samantha Ronson, according to a friend.

Friends of the Mean Girls star say that the actress has been "a complete and utter wreck" since Ronson broke it off with her two weeks ago, and is drowning her sorrows in a sea of men, reports the New York Post.

One friend said that some of the guys include 90210 star Kellan Lutz -- who "has been out of town this week, but they are in constant contact" as well as British paparazzo Chris Jepson.

According to a source, on April 15, Lohan and Jepson were inseparable at a Hollywood Hills house party.

They even went into a bathroom together and didn't come out for quite some time, the source added.

Friends are terrified that Lohan is in a 'meltdown' situation and has no career to fall back on.
