A gaggle of showgirls stopped traffic Tuesday night on La Cienega Boulevard in West Hollywood as CBS hosted its fall premiere party at Greystone Manor.

The high-kicking extras from “Vegas” were on hand to greet the arrival of Dennis Quaid, Michael Chiklis, Jason O’Mara and the rest of the show’s cast. That reception left no doubt about which of the Eye’s new shows has the promo pedestal at the network.

CBS chief Leslie Moonves and wife Julie Chen drew a big crowd inside, as always. “NCIS: Los Angeles” star LL Cool J posed for plenty of photos, but he was one-upped by “NCIS’s” Pauley Perrette, who had her fiance oblige pushy fans with snaps as she made her escape through the valet line.
