If Hollywood were like kindergarten, would Lindsay Lohan struggle in the "plays well with others" category? In a one-hour span during Thursday's surprise Prince concert at New York City club Butter, the 19-year-old verbally sparred with nemesis Paris Hilton, as well as with Diddy, PEOPLE reports in its new issue.
(Hotheads all around: An insider tells PEOPLE that Diddy later had his bodyguards evict Lohan from her own table. "Lindsay did nothing wrong," insists a Lohan source. "She wanted no drama.")
Just last Monday Lohan had another run-in with Hilton at Butter, where the hotel heiress confronted Lohan about dating her ex, Stavros Niarchos.
Then, in the wee hours of Wednesday morning, they battled it out in an all-night dance-off at the club Stereo. "They didn't say a word to each other, but they were literally a foot and a half away from each other the entire time," a source told PEOPLE.
So how should a feisty redhead – or anyone, for that matter – tame a temper? Says anger-management expert Dr. Michele Borba, author of Don't Give Me That Attitude!, "The first step is figuring out your triggers. If you know what's likely to tick you off, you can control yourself when you see it coming."
