The Crash hunk served as guest host on Saturday's (17Apr10) episode of the hit sketch show and proved he wasn't afraid to don drag to draw laughs, dressing up in a short blonde wig and a skin-tight unitard to play muscly weightlifter Olivia Newton Cougar Mellencamp.
He also showed his street credibility as a B-boy in a segment inspired by dance-off movie You Got Served, while he portrayed one half of fictional rap duo Thrilla Killa Klownz in another music sketch parodying the Insane Clown Posse.
And Phillippe wrapped up his appearance on the show by wishing his father a very special birthday.
After thanking the cast and crew for welcoming him onto Saturday Night Live, he turned to the camera and said, "I've had the best week. Happy Birthday dad!".
