Heidi Klum Signs On To America's Got Talent

Heidi Klum has reportedly signed on to become the fourth judge on America's Got Talent.

According to gossip site TMZ, filming will begin on the eighth series of the reality show today.

Sources close to NBC said Heidi had signed up as a judge following “a last minute negotiation” and that the model boarded a plane to New Orleans yesterday, where the show is holding its first audition rounds.

Heidi won't be the only new girl on the panel, as Mel B will be making her first appearance on the show, after being signed up to replace Sharon Osbourne.

The girls join comic Howie Mandel and "shock jock" Howard Stern.

Meanwhile Sharon Osbourne is reportedly being lined-up for a return to The X Factor in the UK.
