Who saw this one coming?

Last year, UK disco crusaders Disclosure dropped Settle, one of the best records of 2013, which spawned smashes like “Latch” with Sam Smith and “White Noise” with AlunaGeorge, among other gems — including “F For You.”

The infectiously catchy throbber is more than enough of a groove to inspire some serious foolery on the dance floor as it stands, but the brother act decided to enlist a new voice — none other than the “No More Drama” titan Mary J. Blige herself — to give the track a soulful blast of energy.

On Sunday, the songstress surprised the crowd at Terminal 5 with a surprise appearance during Disclosure’s set. And just like that, the studio version is already upon us.

The result is essentially a whole new track (or, at least, a more fully fleshed out production) as Miss Mary croons her way through euphoric, lovey-dovey new verses that bring the good ol’ days of ’90’s House queens to mind — think Robin S and Ce Ce Peniston.

“Boy, your love is so beautiful/And I’ll play the fool for you!’ Miss Blige happily swoons.

It’s a solid exchange between the two, providing a boost of major mainstream exposure for the UK duo while giving Mary a chance to have her voice bouncing in a whole new generation’s ears.

Really though, Mary J kills it as a dance diva. Can we recruit the pair to craft her next record?

‘Settle’ was released last June. (iTunes)
