It looks like fans are about to be treated to a special edition of OVO Sound Radio tomorrow. Moments ago, Diddy took to his Instagram page to announce that he’s premiering a new song with Rick Ross & The Notorious B.I.G called “Watcha Gon’ Do” during tomorrow's OVO Sound radio.

“World Premiere Saturday!! OVO Sound Radio!!! Puff Daddy, Rick Ross AND the GOAT, THE NOTORIOUS BIG!!! 6pm EST this Saturday 7/22!! Don't miss it! #BadBoyOVO” Puff’s caption read along with the single’s artwork.

It’s unclear at the moment if the Biggie vocals are unreleased or not, but we’ll know less than 24 hours from now when the song officially drops. Peep the announcement (below) and be sure to check back tomorrow afternoon to hear the song. Who's looking forward to hearing this?
