The story of The Hills’ very own Stephanie Pratt’s Sunday whoopee may have been foreshadowed by the Twitter message she wrote before joining other MTV co-stars at Holly Montag’s birthday party at Hollywood club Empire. “its my sissy @hollymontags bday party! just finished dinner and going to Empire but im pretty tired aka yes i am the party pooper ” she let out, proceeding to make a night of it.

Having made it, the 23-year-old reality television luminary ended up in Van Nuys jail in the small hours Monday. She was busted on the suspicion of driving while drunk at 3:45 am.

The “party pooper” was released several hours later upon posting a bail of $5,000.
