Making the most of their Humpday evening, a smattering of sexy starlets converged on the InStyle Summer Soiree in West Hollywood last night (August 14).

Newly-engaged “Hellcats” actress Ashley Tisdale was all smiles as she showed off her engagement ring and fiancé Christopher French at Poolside at the Mondrian Hotel.

Meanwhile, beautiful blondes Brittany Snow, Julianne Hough and Bella Thorne each took turns posing for the press in their gorgeous getups.

And “90210” stunner Shenae Grimes was in good spirits as she strolled around the arrivals area in a black-and-white-striped referee-styled top with black shorts and black ankle boots.
