Stephanie Pratt: OP Partier

Never one to miss out on a party, Stephanie Pratt was spotted arriving at Mel’s Diner last night (July 7) for the OP launch of their new campaign OPen Campus.

The “Hills” hottie looked excited as she arrived at the West Hollywood eatery, striking a few poses for the paparazzi in her blue button-up/purple shirt combo.

Also in the house was Stephanie’s “Hills” costar Brody Jenner along with his girlfriend, Playboy Playmate Jayde Nicole.

Fellow reality starlets Kim and Khloe Kardashian of the E! show “Keeping Up with the Kardashians” also made an appearance at the shindig.
