Mel posted a message thanking her Spice Girl band mates for their best wishes on her third pregnancy, and named Emma, Mel C and Geri - but NOT Posh.
The Daily Mail reports there could be trouble in Spice World because of Victoria's recent refusal to allow previously recorded material to be released, fearing it will damage her fashion career.
Mel later Tweeted 'I love and support all my spice girls always have!!!' but did her first post
'Ahh big thanks to my spice girls mel c, geri and emma for all the baby well wishes! Love you! Xxxxx' speak volumes?
What do you think?
A genuine mistake? Or too many egos and competing baby-bumps?
