Kathryn McCormick, best known for her recent appearances on "So You Think You Can Dance," has joined the tentatively titled Step Up 4Ever as the female lead.

The casting was announced via Twitter by choreographer Stacey Tookey and subsequently confirmed by Rock of Ages director and Step Up franchise producer Adam Shankman.

"Kathryn McCormick isn't just IN Step Up 4," he writes, "She's the female lead. Her audition was fantastic. A star is born."

Little is known about the plot of the Summit Entertainment sequel, but late last year, an ad was placed in Variety announcing that the project was planned for 2012 and music video director Scott Speer was subsequently brought aboard to direct.
