The CW has tapped a familiar face as host of its summer dating game series Perfect Score. Arielle Kebbel, who has been recurring on the network’s The Vampire Diaries and 90210, will make her unscripted series debut emceeing Perfect Score, from FremantleMedia North America. Created and executive produced by Scott St. John (America’s Got Talent), Perfect Score is a dating game show with cash prizes. In each half-hour episode, two friends compete to see who can pick their ideal mate from a group of 12 prospective singles after both the players and the contestants have taken compatibility tests. The player who selects the most compatible single — with the highest cash value — wins the cash prize and the date. Kebbel, repped by Paradigm and Principal Entertainment, also co-starred on the CW’s Life Unexpected and recently served as a correspondent for E! Countdown To The Oscars.
