Instagram photos spark speculation...
Disclosure, Madonna

Taking their house sound out on the road, Disclosure have been able to work with all manner of new artists.

Unveiling a Bishop Nehru collaboration, the brotherly duo then enlisted Mary J Blige for a new rendition of 'F For You'.

Flying back out to the United States, Disclosure now seem to be getting a little close to Madonna. (via FACT)

The Queen of Pop spent the weekend posting pictures on her Instagram, joking about getting "promoted to head of security for Disclosure!"

Earlier this year, the singer used Instagram to unveil collaborations with Diplo and Avicii.

Could she be doing the same with Disclosure? Time will tell...
