Tonight is "Party Anthem" night, which means earworms aplenty.

Redfoo, from LMFAO, is a guest judge. In case you find it difficult to call a grown man "Redfoo," his actual name is Stefan Gordy, as he's the youngest son of Motown founder Berry Gordy, Jr.

The entrance song this week is "Party in the U.S.A." by Miley Cyrus, and it's got a carnival theme. So of course the Chmerkovskiy brothers are in leather letterman jackets with no shirts on underneath.

Erin Andrews is back in her regular garb of sleek and chic and I feel better.

After Tom Bergeron does a treeeeemendous job of rolling the initial R in his name, Redfoo enters to "Party Rock Anthem." Redfoo is wearing knee-length sequined shorts,a red leather jacket with sequin and leather accents, lens-less white rhinestone studded glasses,and no shirt. This man is 38 years old. Tom calls Redfoo "the only guest judge to make Bruno look like an accountant."

NeNe and Tony are safe.

In rehearsal footage, NeNe's barefoot; Tony is in sneakers, and she towers over him. Which is curious, given that Google says she's 5'10" and he's 6'1". SOMEBODY'S lyin'.

NeNe's got the hip action for sure, but her footwork and legs are so imprecise. Wonder if the judges will mention that?

Len Goodman tells NeNe that if she wants to go further, she'll need to work on her technique and then mentions her footwork. HA! Len gets me.

Bruno Tonioli, wearing a sequined tuxedo jacket, rips it off to reveal a skintight spandex t-shirt. I think I'd like the shirt better without the giant logo in the center. Bruno says the footing was shaky, but the momentum of her hips carried her.

Tom asks about Bruno's "nipples popping," to which Bruno responds, "If you got it, flaunt it."  This ballroom is going wild early tonight.

I love how awkward Tony gets when he's shirtless. It's rather endearing, especially since his torso is nothing to be embarrassed about.

Scores: Carrie Ann: 8; Redfoo: 9; Len: 8; Bruno: 8

Redfoo's paddle has pink and black tiger stripes on it. That seems inappropriate.

We're danced back in to "Party Anthem" night with "Do You Love Me?" by The Contours.  If you're of a certain age, that song is forever associated with "Dirty Dancing."

James & Peta are safe, but Candace & Mark are in jeopardy.
