BONNIE'S "DUB" STEP: How many lip-synching stars can you spot in the "celebrity dub" video for Kemosabe/Epic artist Bonnie McKee's "American Girl"? Let's just say any clip that features Ke$ha, Macklemore, Katy Perry, George Takei and Joan Rivers is in a category of its own. A few YouTube commenters predict the song, produced by Josh Abraham and Oligee, will be this summer's "Call Me Maybe" (which also began its life with star-studded lip-dub videos). We won't weigh in on that question. McKee is repped by Pulse Management. (6/27p)
