Mel B hasn't given up hope that Victoria Beckham and Mel C will be part of The Spice Girls reunion

Victoria and Mel C - known as Posh Spice and Sporty Spice in the band - have both publicly ruled themselves out of the reunion, with Posh wanting to focus on her fashion label and Sporty concentrating on her solo music.

However, Mel B has hinted there still maybe a chance the two members could be convinced to be part of the Spice Girls' get-together.

Quizzed on what was happening with Victoria and Mel C on Australian breakfast TV show 'Sunrise', she quipped: "I killed the other two!"

Mel B, 41, then added: "Who said they're not going to possibly be involved? Until it actually gets going, everything's a bit up in the air."

Admitting she is "bored" of the questions about the Spice Girls reunion, the 41-year-old singer insisted people just needed to wait for the plans to be finalised.

She said: "Until we've got something to announce, it's the same old, same old. We are looking to do something, it's just a case of when."

The 'I Want You Back ' hitmaker was less than impressed when hosts Kochie and Natalie Barr suggested her fellow 'The X Factor Australia' judge Iggy Azalea could join the group.

She exclaimed: "There's only five Spice Girls in the whole entire world, and that's it, so zip it!"

Mel B - full name Melanie Brown - was also quizzed during the TV appearance if there is any tension between her and Iggy on the panel of the talent show and she told the hosts to stop trying to cause trouble.

The outspoken star - who is also joined on the panel by Guy Sebastian and Adam Lambert - said: "She's got a massive career, she's highly successful, and we get on. I know you're trying to get some rivalry between me and Iggy, but there isn't any. Maybe there will be soon."

At the end of the interview, Kochie wrapped things up by saying: "Don't miss Mel on 'X Factor', 7:30 tonight - how will she and Iggy get on?"

And that prompted Mel B to jokingly storm off set as she said: "Oh gosh, what is all this? I'm leaving!"
