Last night, Jennifer Lopez performed her terrible single “Louboutins” on the So You Think You Can Dance? finale. This is the same song that Jennifer famously performed at the AMAs, when she fell on her ass after attempting some kind of jump onto her dancer’s back. Jennifer later said she “meant to do that” but she was probably just joking - and, after all, that one fall was enough to get her quite a bit of attention for her new album, and for the single.

Anyway, Jennifer managed her performance last night without busting her ass, and she actually gave us some half-decent dance moves (see video above). Here’s the thing - remember when Jennifer could really dance? Like, fly girl dancing. Now she seems kind of stiff - she’s still got something, but it seems weaker. I feel the same way about Britney, by the way. It’s like their moves are just a second too late, or they’re rusty or something.

Jennifer’s bit was pretaped, and Page Six had the behind-the-scenes report:

Jennifer Lopez was in fine form at yesterday’s taping of her dance performance for the finale of Fox’s “So You Think You Can Dance?” “She brought Marc Anthony and the kids along to watch, and she kept going over to the microphone to talk to them between takes,” says an observer. “The audience was eating it up. It was very cute.” Lopez, who sang her new single, “Louboutins,” showed no sign of letdown after her minor tumble at the American Music Awards. “She nailed it,” says our spy. “Even the background dancers were impressed.”

By the way, if you wanted to know who actually won SYTYCD, Entertainment Weekly has a big recap of the show… obviously, there are spoilers on the link if you didn’t see it last night. All EW said about Jennifer’s performance was that is was a “very indulgent, very sparkly performance piece” which “was mostly forgiven because she included SYTYCD alums (I spotted Kayla, Karen, and maybe Courtney from season 4?) in the mix.” That’s all Jennifer got! She should have busted her ass again, then she would have been talked about all day.
