Heidi Klum doesn't put off though without Smokey Robinson, her singing partner

It's a scheduling conflict that Heidi Klum became alone from her singing partner Smokey Robinson in a show on Thursday. They were set to perform the Temptations's My Girl at the fundraiser in Los Angeles.

Though her partners absense Heidi Klum wasn’t put off from the Thursday night’s celebrity karaoke benefit, UNICEF Playlist, in Los Angeles. Robinson couldn’t make the event but Klum took to the stage anyway and told the crowd, “Smokey stood me up. He was supposed to sing ‘My Girl’ with me. Will anybody else sing with me?”

Host Tom Bergeron, suggested, “How about instead everyone in the room helps you out with ‘YMCA?’ ” Village People hats and props were brought out and Tom Hanks quickly grabbed a cowboy hat, and later a construction worker’s hat. Rita Wilson, Wayne Brady, Jon Huertas and Seamus Dever quickly got in on the action. Other celebrity performers at the bash included pregnant model Molly Sims, who

belted out Madonna's Papa Don't Preach, and Desperate Housewives stars James Denton, Kyle MacLachlan and Doug Savant, who teamed up to sing John Mellencamp's hit R.O.C.K. in the U.S.A.
