gym workout sunglasses Kendra Wilkinson dancing with the stars

Kendra Wilkinson is enjoying her comfy clothes … flip flops and all … before the hardcore costume fittings begin for the upcoming season of Dancing With The Stars. Ms. Wilkinson will be getting her groove on with dancing pro Louis van Amstel!

The former Girls Next Door, and mom of 1-year-old son Hank, is just about back to her pre-baby Playboy Playmate size, and with all of this dancing, she's going to be looking like the old-school Kendra we fell in love with years ago.

Kendra is following in the footsteps of her former Girls Next Door co-star Holly Madison who was part of DWTS back in 2009.

We can't wait to see Hank Baskett's wifey shaking her tight tushy on the dance floor!
