InStyle threw a Summer soiree at the London Hotel in Hollywood last night. Editor Ariel Foxman played host to a range of starlets, including Ashley Tisdale, Nikki Reed, and a Ted Baker-clad Sophia Bush. Malin Akerman and Jaime King both made the scene, too, each wearing red dresses. Jaime, who donned Marchesa, arrived on the arm of her husband, Kyle Newman, while an Erin by Erin Fetherston-clad Ashley made the rounds, getting compliments on her braid, with boyfriend Scott Speer. Jordana Brewster broke from promoting her new show, Dallas, to hit the town. After posing on the carpet, the ladies moved to the hotel's rooftop to mingle with male attendees like Peter Facinelli and Derek Hough.
