Los Angeles, Oct 19 (THAINDIAN NEWS) The 23-year-old star of MTV reality show, The Hills, Stephanie Pratt, was arrested early on Sunday morning on suspicion of driving under the influence reports the AP.

Stephanie Pratt spent a wild Saturday evening at a birthday party in Hollywood for Holly Montag. She was out with some fellow “Hills” stars at Empire, celebrating Holly Montag’s 26th birthday.

Pratt was arrested her outside the birthday party venue in Hollywood and booked into a jail in the San Fernando Valley. She was released several hours later after she posted a $5000 bail, according to Sergeant Mark Cohan of the Los Angeles Police Department.

However, there are conflicting reports about her bail as some reports suggest otherwise too. “Pratt was released with a ticket later Sunday morning and was not required to post bail but will return for a court hearing”, according to a spokesperson at the Van Nuys Division, where Pratt was held.

Before heading for the infamous birthday party, she had tweeted, “It’s my sissy @hollymontags bday party! Just finished dinner and going to Empire but I’m pretty tired aka yes i am the party pooper :(”

While the birthday party was in progress, then E! News caught up with her, “I’m a party pooper tonight,” Pratt said. “I got bad news this morning. A friend passed away in a car accident, so everyone needs to drive safe.” This is ironical indeed as some time after this drive-safe statement she was arrested for DUI.
