Has Spice Girl Mel B caused rehearsal chaos?

Mel B has reportedly thrown the Spice Girls' reunion tour rehearsals into chaos after making it to the finals of Dancing With The Stars.

The mum-of-two is desperate to win the US version of Strictly Come Dancing and has spent hours practising her moves with partner Maksim Chmerkovskiy - and her dedication to the show has apparently caused problems in the Spice camp.

The band launch their tour in Vancouver on December 2, six days after Mel competes in the TV final next Monday, reports the Sun.

"The opening night is days away yet there hasn't been much time for rehearsals," an insider told the newspaper.

"A lot of Mel's time has been taken up with preparations for each Dancing With The Stars.

"The girls are really proud of her but at the same time they're worried that Mel will give her all to the dance show and be exhausted for the start of the tour.

"Rehearsal time has been cut down a great deal because of Mel's commitments to the TV show. It's not ideal."
