Things are going from bad to worse for Lindsay Lohan.

The Wild Child seems to have lost the plot, after apparently ‘going crazy’ when she learnt that her former girlfriend Samantha Ronson had jetted of to Cabo to attend Nicole Richie’s party.

According to kickster.com, Lohan “went crazy” trying to track down the whereabouts of her ex-lover and who Sam’s companions were as “couldn’t get permission to leave the country,”- and the minor detail that she wasn’t invited to the celebrations.

Sources have told kickster.com said that Li-lo is still not over her relationship with Sam and is still obsessive over “trying to track down Sam.”

The latest news doesn’t bode well for Lohan who could be facing a jail sentence following her failed drugs test last week.
