Heidi Klum joins ‘America’s Got Talent’ as judge

Heidi Klum is adding a new show to her already busy schedule: She’s joining “America’s Got Talent� as a judge.

Klum will be joining returners Howard Stern and Howie Mandel as well as the recently announced judge Mel B. It will be the first time the show has used four judges. Former judge Sharon Osbourne left the show after last season amid a dispute with NBC.

But have no fear, the new judging job doesn’t mean Klum is giving up her role on her other long-running reality competition program, “Project Runway.� That show began its 11th season in January and she remains on board as judge and host.

“I’m really excited to join the panel of ‘AGT’ to see it all -- from the ridiculous to the fantastic,� Klum said.

Auditions around the country for the show’s eighth season begin this week.

This isn’t the first time a long-running reality show has added a fourth judge hoping to boost ratings. “American Idol� also introduced a fourth judge, Kara DioGuardi, in its eighth season.
