It's the question that refuses to go away: Does Real Housewives of Beverly Hills star Lisa Vanderpump have butt implants?

Talk show host Wendy Williams pounced on the chance to ask Lisa that question when her guest, Kyle Richards, crank called Lisa on Tuesday's show.

"Let's go back to the butt implants," says Wendy. A sleepy Lisa — it was about 7 a.m. on the West Coast — responds: "There is nothing in my butt. I will bring my butt to you personally next time I'm in New York, and you can examine it."

Kyle jumps in to say she's gotten a little "squeeze" in there too. And we know Lisa offered her behind for Chelsea Handler to inspect too!

So does everyone get to check out Lisa's behind?
