"KEEP that train wreck away from me!” A furious KATY PERRY shouted that order after bisexual bad girl LINDSAY LOHAN tried to latch on to her at a recent roller skating party hosted by the singer.
Things spiraled out of control quickly at the Glendale, Calif., rink during a July 14 party the 27-year-old threw for her friend, stylist Johnny Wujek.
Lindsay showed up uninvited and “dressed like a bag lady” at the ’90s-themed bash, said a Hollywood insider. “She started acting really weird.
“She refused to talk to anyone and she kept following Katy around, trying to take a photo with her. Katy told friends, ‘I think she may be drunk, so PLEASE keep her away from me!’ ”
But it got worse as the 26-year-old “Mean Girls” star – who’s been in rehab at least five times – began catching up to Katy as they skated around the rink.
“Lindsay was hell on wheels!” said the insider. That’s when, in utter desperation, the singer turned to a staffer and shrieked about keeping that “train wreck” off her back.
But the roller-rink party ended on an upbeat note for the “California Gurls” singer, “who had a blast,” said the source.
“She hates to hurt people’s feelings, but she’s the first one to tell you she’s avoiding all ‘Debbie Downers’ – and Lindsay was reeking of negativity.
“She finally took the hint and left.”
