Pratt of The Hills Arrested for DUI

Early Sunday morning, Stephanie Pratt, star of the MTV program The Hills, was arrested on suspicion of DUI, the Los Angeles Police Department says.

Saturday night, Pratt allegedly attended the birthday party of her fellow cast member Holly Montag. At 11 p.m. that evening, Pratt posted in her Twitter account, "It's my sissy @hollymontags [sic] bday party! I just finished dinner and going [sic] to Empire but i'm [sic] pretty tired aka yes I am the party pooper"

According to police records, the 23-year-old reality TV star was arrested at 3:45 a.m. and charged with the drunken driving offense. The Associated Press reports that she was booked at Van Nuys jail and released around 10:30 a.m. on $5,000 bail.

"It was your basic DUI," Sergeant Sal Oraz told People Magazine. "Our traffic officers driving down the street spotted her and pulled her over. She was cooperative and there were no issues with her arrest."

In accordance with California law, Pratt will likely be eligible to have the DUI offense removed from her record if she successfully completes a probation program.
