*Although news broke early of Ellen DeGeneres being a surprise guest on Thursday’s finale of “So You Think You Can Dance,” the talk show host still managed to raise some eyebrows with her performance of the season’s most popular routine.

The comedian replaced injured contestant Alex Wong opposite All-Star tWitch to perform a hip hop number to “Outta Your Mind” by Lil’ Jon and LMFAO.

According to reports, Ellen and tWitch spent the past month secretly rehearsing the choreography, which was amended a little – okay a lot – to accommodate Ellen’s limited ability. But the crowd loved it anyway and the judges gave her a standing ovation.

When Alex hobbled out on crutches to congratulate her, Ellen said: “I have had so much fun and it broke my heart when I saw the injury. As a joke, I said it’d be fun to do [the routine] and it became a reality.”

The season 7 crown went to 18-year-old Lauren Froderman, with 18-year-old Kent Boyd in second place and Robert Roldan, 19, in third.
