Some members of the girl group - which includes Mel B, Mel C, Emma Bunton, Geri Halliwell and Victoria Beckham - were hoping to reunite this year to mark two decades since the release of their debut album but Mel B has now revealed they have been forced to shelve plans until 2017.

Speaking on Live With Kelly, she said: "It's our 20th anniversary this year - this would be the perfect year but places get booked out, so what we're hopefully doing is planning on doing something to celebrate next year.

"It's something that we want to do and it'd be nice to celebrate and give thanks to all the fans. I'm not getting any younger. Let's hurry up and get this done."

Meanwhile, the 'Wannabe' hitmakers are reportedly planning on documenting their comeback for the small screen.

A source said at the time: "The Spice Girls comeback is the big story in pop so it's no wonder the girls want to maximise their popularity. There is certainly a big audience for it. BBC, ITV and Sky will no doubt be fighting it out for the rights. The girls are always good value, so there will be plenty of material."

And Simon Cowell is "desperate" to help the group release a new album.

A source shared: "Simon is desperate to make a new Spice Girls album. He doesn't want to miss out after the first time around. He spent the X Factor auditions last week quizzing Mel about the band and said he would do 'something mega' if they signed with him.

"He kept asking if they were going to be producing new music and said if so, he wants to do it with them. He even went as far as warning Mel that they'd better not talk to any other labels before meeting with him. Mel deliberately kept coy and told him they 'hadn't finalised everything', but he wouldn't leave it alone."
