Stephanie Pratt, of “The Hills,” introduced her new milkshake at Millions of Milkshakes in Los Angeles yesterday. Remember when Spencer and Heidi mixed up their own shakes? Well, yesterday little sitter got a chance to add a signature shake (called Steph's Slumber Party) to the menu.

“Thank you to everyone who showed up!! My milkshake “Stephs Slumber Party” is now available at Millions of Milkshakes!! Sooo awesome!!”
