Kendra Wilkinson has a new favorite asset!

"I can't stop lookin' at my new booty," she Twittered on Wednesday. "Damn, I'm so happy!"

So, how did the reality star — who gained more than 50 pounds while pregnant with Hank IV, her son with hubby Hank Baskett — get her behind in shape?

Perhaps it was her quick moves on the soccer field in L.A. on Tuesday, under the encouragement of her trainer Nicky Holender.

"OMG, I'm so tired," she Twittered after the practice. "Just played a soccer game in 85-degree weather."

The new mom has admitted to Us Weekly that she struggled to accept her post-baby body in the weeks after giving birth in December.

"Having a different body was such a culture shock," she told Us. "I'm so used to being hot and fit."

Still, the one-time centerfold added that her body confidence has been off.

Wilkinson, whose breasts went from a 34C to an E, told Us: "I love my legs, and I love my butt, but everything else I hate."
