Heidi Klum looked stunning at the "America's Got Talent" season 8 quarter-finals at Radio City Music Hall in New York City on Wednesday. The talent show judge rocked a sparkly silver dress with a plunging neckline. She swept her hair back and wore large hoop earrings.

Last night the talent show featured the quarter-final eliminations, and the final 20 acts will now head into next week's semi-finals.

Klum is also starring on season 12 of "Project Runway," and designer Zac Posen and Tim Gunn visited her at Radio City last night.

The model has been making headlines this summer for her sexy, nude snaps on Instagram. It was later revealed that her mother has been the photographer behind many of the topless photos.

Her explanation for letting it all hang out? "I don't like wearing tops. And I don't like tan lines," she told Access Hollywood last month.
