U2's Bono To Collaborate With Spice Girls?

U2 frontman Bono has reportedly written a song for the Spice Girls to coincide with their reunion.

The song is expected to feature on the group’s forthcoming greatest hits album – which is pencilled in for release on November 5th.

According to the Mirror, the U2 singer has been brought in by the group’s record label to ensure that the album sells as many copies as possible.

A ‘source’ told the paper: "There's been a bit of unease as to how the album will perform and if there's still a solid Spice Girls' fan base out there.

"However Bono's involvement has lifted the whole camp and he's delighted to have been asked and add his experience."

As previously reported on Gigwise, tickets for the Spice Girls reunion show in London sold-out in 38 seconds earlier today, prompting organisers to add three more shows at the O2 Arena. 

The group will now play the former Millennium Dome venue on December 15th, 16th and 18th before returning on January 2nd for a final night. 

Tickets have since appeared on eBay for as much as £500.
