Celebrity gossip TMZ is reporting that Terry Semel‘s daughter Courtenay, formerly linked with actress Lindsay Lohan and currently dating MySpace and reality show star Tila Tequila, was arrested in Las Vegas last night.

The incident occurred at the club Pure at Caesars Palace, and Courtenay is alleged to have hit a Pure security guard in the back of the head with her purse. Caesars’ security force detained Courtenay until police arrived and arrested her, issuing a citation for battery.

Daddy must be so proud. Then again, this sort of press may actually make him feel better about the press he got during his tenure at Yahoo.
