Fergie, Lady Gaga and Mark Ronson might be cooking up the best collaboration of the decade.
Fergie and Mark Ronson were seen making music together last night when the above photo showing the singer crooning beside the piano-playing producer was posted with the caption "Saturday Night Mashup: Fergalicious meets Uptown Funk."
Details of the singer's long-awaited sophomore solo record are being kept top secret but was believed to be dropping in April, so it's likely that they're just putting finishing touches to a song.
However (here's where it gets more interesting), Lady Gaga was also spotted with Mark Ronson last night as they left a recording studio together.
Singer Lily Allen previously revealed that Gaga and Ronson were working together on the highly-anticipated follow-up to "ARTPOP."
Two separate sessions in one night wouldn't be out of question for the Grammy Award-winning producer - who's probably in very high demand right now - but we prefer the thought of a collaboration by the two singers.
With both Fergie and Gaga making huge pop comebacks this year, a duet produced by the "Uptown Funk" hitmaker could be magical.
