Heidi Klum Sings Karaoke For UNICEF Children's Relief Fund (VIDEO)

The end of her seven-year marriage was the thing making headlines until Heidi Klum gave fans a more benevolent story to talk about Thursday.

The supermodel donned a feather headdress and belted out "Y.M.C.A." at UNICEF's Playlist with the A-List event in Los Angeles. Her karaoke jam benefitted the Children's Relief Fund, which provides health care, education, clean water, nutrition and emergency relief to young people in need.

But Klum didn't perform solo. She got some help from a few big names, including Smokey Robinson, Kristin Bell and Tom Hanks.
