This week’s episode of the award-winning HBO hit series ‘Entourage’ had cameo appearances from Katie Morgan, Cassie Young and Digital Playground’s Shay Jordan.

The episode, “Tree Trippers,” debuted Sunday night and will be reairing on the various HBO channels throughout the week. Morgan plays herself in the episode riding in a convertible with Jordan and Young. They encounter the cast of the show who are on their way to the Joshua Tree desert in Eric Roberts’ RV in search of an answer. When they see Katie, who also hosts an HBO sex series, they call her out by name. The three girls flash the cast before speeding off.
