On Monday, Geri blasted rumours of a rift between her fellow Spice Girl bandmates as they prepared for their impending tour. 

Hot on the heels of bombshell lesbian claims by Mel B, as well as Scary Spice's recent health woes, Geri was quick to dismiss the supposed drama, telling critics: 'You think, "Oh f*** off!"'

Speaking to The Sun, Geri revealed that they were all 'having a blast during rehearsals' and their relationship was 'really good and positive.'

The tour, which is set to commence without former bandmate Victoria Beckham, was also rocked by Mel B's admission that she had sex with Geri

However, Geri revealed that fans had nothing to worry about as she spoke of her bandmates: 'Our relationship is really good. We’ve all been really positive, so it’s nice. It’s natural. I’m really happy, everyone’s happy.'

Look at that!  One delighted fan also tweeted an incredible look at the band's stage, as over 58,000 fans flocked to the Dublin stadium

When asked if they would be celebrating during rehearsals, Geri explained: 'That’s exactly what we’ll be doing, with all of our imperfections, all our faults, but celebrate the good bits too. No one is perfect but it’s all fine. We’re having a blast. It’s an absolute laugh.

Meanwhile, Mel B is reportedly doing fine after being rushed to hospital following her complaint that she was 'totally blind'.

Giving an update on the singer's health woes, a source has told PEOPLE: 'She’s doing fine now, she’s not blind. This has happened before. She has herpes in her eye, so this can happen.'

It was also added by the source that despite the singer, 43, complaining to doctors that she couldn't see, her 'eye is OK' and 'they've given her some drops and she’s good now. It was nothing major.'
