Tonight, So You Think You Can Dance sets up shop in Las Vegas for the first of two episodes that narrow down the field of hopeful hoofers to the Top 20.

During last week’s Memphis and Miami tryouts, The Veronicas‘ “Take Me On The Floor” played through one of the show’s “Here’s your ticket to Vegas” montages. With an electro-pop sound not unlike fake-lesbian Russian duo t.A.T.u, Aussie twins Jessica and Lisa Origliasso crib even further, teasing listeners with a little lyrical bisexuality (“I wanna kiss a girl, I wanna kiss a boy”):

With this week’s Rolling Stone cover story revealing that Lady Gaga’s “Poker Face” is about her desire to sleep with a woman while dating a guy and Katy Perry’s ditty about sampling the fairer sex, few females in pop music appear to be playing it straight these days. (Not that there’s anything wrong with that.)

So You Think You Can Dance airs tonight at 8/7 Central on Fox.
