Simon Cowell will unite the world of pop to raise money for those impacted by the tragic Grenfell tower fire.

The*X Factor*boss has put together an all-star line-up of pop superstars — including Liam Payne, Lily Allen, Skepta and James Arthur— for a charity cover of the Simon and Garfunkel classic 'Bridge Over Troubled Water' to benefit the families of those who died and the survivors who were left homeless after the horrific fire.

Fans will be able to purchase the track on Monday, with the government waiving all VAT costs. ITV is set to premiere the 'Bridge Over Troubled Water' video in primetime next week.

Also taking part in the track will be The Who, Emeli Sandé, Skepta, Louisa Johnson and Craig David, with Cowell stressing that he's still in talks with other artists to sign on.

"Until that last note has been finished, we will not be off the phone," the music mogul told*The Sun.

Cowell first announced*late Thursday (June 15) that he'd be staying up to make calls in order for such a huge fundraiser to be made possible.
