The incident occurred after 3 a.m., after Semel left Pure Nightclub at Caesars Palace with friends. She returned after the club closed and complained to a security guard that she had lost her cell phone.

Semel, who has been romantically linked to Lindsay Lohan and reality TV star Tila Tequila, was cited for battery after slapping the guard on the back of the head, according to a source.

She was detained by Caesars Palace security and given an early October court date.

Semel, 28, appeared in E!'s reality TV series "Filthy Rich: Cattle Drive" in 2006 with Kardashian and a roster of super-rich kids. Semel and Lohan dated late last year before the "Mean Girls" star developed a relationship with DJ Samantha Ronson.
