In a story about a police report that Paula Abdul filed in Hollywood on Tuesday night concerning some incidents that allegedly took place late Saturday, Us Weekly might have inadvertently stumbled on a new reason that the loopy American Idol judge appeared typically zonked on this week's shows: a concussion. Said Abdul to the cops about the late-night party:

She said a man at the party grabbed her by the arm and threw her against a wall. She claimed to have a concussion and spinal injuries. She told officers that she sought her own medical treatment and that she would agree to have her injuries photographed at a later date." The LAPD are investigating her claims and will not release the name of the suspect pending investigation.

Us has learned that the night also ended with Abdul's ex-boyfriend Dante Spencer in the hospital. According to a source, last Saturday night Abdul and friends headed to Xenii (a floating after-hours party held in a different location each week), where she ran into former CAA agent Jim Lefkowitz.

Lefkowitz took offense to Abdul's "smirky attitude," and after a heated discussion, the agent "accidentally-on-purpose bumped into her" so hard that Abdul ended up sprawled on the floor. Spencer then rushed to Abdul's defense and punched Lefkowitz in the face, our witness says. A shaken Abdul was taken home, complaining of pain in her lower back and a possible concussion. Spencer was driven to the hospital where he received stiches for a cut below his eyebrow.

At the hyperaggressive CAA, the stiff shoulder-check would merely be their way of saying, "We want to be in the Paula Abdul business," so it's unfortunate that the former agent's hard-to-shake old habits were misinterpreted and resulted in regrettable violence.
