According to reports, she will join judges Howard Stern and Howie Mandel.
A source said: “Simon (Cowell) loves trying people out on his shows, Mel’s already been a judge on X Factor Australia and it’s too far for her to keep taking the kids.
“She did want to do X Factor UK, but Simon really wanted her to do America’s Got Talent.
“She’s outspoken and never afraid to speak her mind, she makes for good TV. NBC execs will be watching through their eyes – let’s hope they won’t be using the delay button on live TV.”
Other recent media reports indicated she wanted to stick with The X Factor in Australia, but visa issues were forcing her to return to Los Angeles.
Update: Foxtel press release:
America’s Got Talent has found its new judge with Spice Girl Mel B (Melanie Brown) joining the judging panel for the upcoming eighth series of the hugely popular reality competition series.
Mel B, known as Scary Spice in the all-girl singing group, will take a seat beside Howard Stern and Howie Mandel, critiquing the show’s wild variety of performers. She replaces the show’s longtime judge Sharon Osbourne, who announced she was quitting last year.
The pop singer brings a wealth of experience to the role, having served as a judge on the Australian version of The X Factor and guest hosted on the UK version.
“Australian audiences know and love Mel B and her larger than life personality and now they can continue to see her on America’s Got Talent, exclusively on FOX8” said Brendon Moo, Foxtel’s General Manager General Entertainment Channels.
“There’s no doubt Mel B will spice up the judging panel with her strong point of view while bringing a fresh youthfulness and currency to this popular series.”
America’s Got Talent is currently holding auditions across America, and will air in both the US and Australia (exclusively on FOX8) mid-year.
