According to The Mirror, Britney gets paid £195,000-per-show for her residency at Planet Hollywood Hotel & Casino, with Bunton telling The Metro that it would take a large sum to get all five girls back on stage.
Baby Spice said: "I'd go to Vegas - if we get paid more than Britney. After the Olympics, it was really hard to think, 'What can we do next?' We represented our country, it was huge! We like to say never say never, so we'll have to see."
The blonde babe went on to add that seeing as all the girls are mothers now, their families would be the biggest obstacle when it comes to a jaunt in Vegas.
Emma added: "I mean, we've all got children, so travelling with them... but, who knows, at the moment we're happy doing our own things."
"I was so proud to do it; proud to be British...That was a perfect time to say, 'That's great. Thank you to everybody, but no more.' Sometimes you've got to know when it's time to leave the party."
While VB may be less than keen to rekindle Girl Power, Mel B, Geri Halliwell and Mel C have all expressed their desire to reunite, with Sporty Spice teasing a possible get together in 2016 to celebrate the 20th anniversary of Wannabe.
