Los Angeles - Former Spice Girl Mel B will join the judging panel on summer TV talent show America's Got Talent, broadcaster NBC said on Thursday.

The 37-year-old Briton, known by the nickname Scary Spice when she was part of the chart-topping 1990s British girl band, will replace Sharon Osbourne who quit the series in a dispute with NBC over their decision to drop her son Jack from another reality show.

Mel B, whose full name is Melanie Brown, will join โ€œshock jockโ€ Howard Stern, who has agreed to return for his second season, and comedian Howie Mandel.

โ€œThis exciting addition of the dynamic Mel B to our lineup of judges promises that fans will see a strong, talented and opinionated woman match up against our equally outspoken judges Howard Stern and Howie Mandel,โ€ NBC president of alternative programming Paul Telegdy said in a statement.

Mel B said she was thrilled to join the talent show, adding in a statement: โ€œIt's so exciting to be bringing some Girl Power to the panel!โ€

The singer recently finished a two-season stint as a judge on singing contest The X Factor, which like America's Got Talent was created by British entrepreneur Simon Cowell.

NBC said nationwide auditions for the new season of America's Got Talent will start on March 4 in New Orleans.

The network is seeking to turn around a fall in audiences last year when the finale in September was watched by a record low of under 11 million viewers, according to ratings data.

The show remained the top-rated summer series among adults aged 18-49, the demographic most coveted by advertisers.

NBC attributed the overall 2012 audience decline partly to an earlier start that pitted Got Talent against end-of-season original programming in May and the start of new TV shows in September. - Reuters
