Elizabeth Hurley is ready to turn the sex factor even higher on WB's hit show Gossip Girl.

The 46-year-old stunner is the new cougar in the Upper East Side ... and it looks like she'll be sinking her fangs into the oh-so-delicious Chace Crawford.

With her gorgeous style, Elizabeth is going to fit into the show perfectly. Plus, that form-fitting red dress is to die for! We have a feeling Blair Waldorf would approve. XOXO
