Nearly two months after her Southern California
mini-tour in early May, Britney Spears
is getting ready to hit the stage again.
June 30 at L.A.'s Greek Theatre, she's due to join Cyndi Lauper, Erasure, Debbie Harry, The Dresden Dolls, The MisShapes with special guest Jeffree Star and host Margaret Cho live onstage for the "True Colors" concert tour, Spears's choreographer, Misha Gabriel, tells PEOPLE.
Friday at the Millennium Dance Complex in North Hollywood, the pop star held final callbacks to find the two male backup dancers she'll add to her act.
Only snag, she never showed up.
The plan had been for Spears to select two guys (out of 21) to join her in the choreographic number she'll perform at the Greek.
Instead, however, she put her two longtime trusted female backup dancers – Criscilla Crossland and Lark – in charge of the process. The two videotaped all the aspirants, for Spears to observe and select at a later time.
Earlier, on June 7 (also at Millennium), Spears was there to oversee auditions herself, with nearly 150 men seeking to pop, lock, whack, vogue, b-boy, breakdance, robot and moonwalk their way into her heart.
Those who were put through paces that day did so to Spears's new, as-yet unreleased song.
As dancer Sam Pete, 25, described the tune to PEOPLE: "It was dope. It reminded me of that one song you hear at 1:50 a.m., when they call last call at a club, and it's the hottest, nastiest song you've ever heard in your life and you've just got to put your drink down and dance to it. You've got no choice. Your body is insisting on it."
