LISA Vanderpump got a temporary tattoo of a penis inked on her chest during a wild episode of Overserved.
The alum, 60, let her dinner guest, Jackass star Steve-O, draw the phallic shape on her with blue marker after losing a bet.
, Steve-O, 46, and comedian Margaret Cho, 52, had to race across Lisa's pool on giant floats while using a ladle to row in an Olympics-style game.
Steve-O triumphed and got the chance to ink the X-rated tattoo on Lisa's chest.
She said, "I think I'd rather have it on my chest than my face," before asking despairingly: "How did I get into this mess?"
Steve later evened out the score by snorting chilli powder, as Lisa looked on gleefully.
The star quipped: "I feel so much better about the d*** on my chest."
Earlier in the show, Steve-O recalled the gross moment he knew his girlfriend Lux Wright was the one for him.
As the trio tucked into a delicious Greek-style spread, he warned: "I'm sorry. This isn't really table conversation."
Lisa prompted: "Go ahead."
He explained that he knew Lux was special because she didn't flinch while filming him defecating on an industrial fan in a segment called "The S*** Hits The Fan.
Steve-O recalled how Lux "kept filming" and even "moved in for a better shot" to capture him relieving himself after not going to the toilet for three days.
