It looks like Drake will be featured on Thug and 21's upcoming collab, which seems to be called "Issa." Thugger's fiancée Jerrika Karlae tweeted about Drizzy being on the track, and though she deleted the tweet, you know the Internet catches everything.

Original Story:

21 Savage and Young Thug's Hihorse'd Tour ends today in New York City. It looks like the two have been working on new music while on the road together.

A clip of a new Savage and Thugger song has surfaced on Thug's Instagram page. In the video, YT prepares to hop on a private jet. But not before rapping a snippet of the collab for the camera, while balancing a double cup. The song is presumably called "Issa."

On the track, the Slaughter Gang rapper spits over a heavy trap beat. "It's a painting,. half a ticket/It's a Kylie, might be Jenner/It's a jet, it's a check/It's a savage, now she wet/It's a Pyrex, I got crack/It's a cooling system, it's a tech/If your bitch spend the night it's a set/If your watch ain't cost 100 it ain't shit," he raps, adding more fuel to the Tyga, Kylie Jenner situation.

Last month, Thugger previewed another song featuring 21 in a similar circumstance. While boarding another private jet between show stops, Thug and his crew, including TM88, participated in a Mannequin Challenge while playing the new track.

Could we be getting a new joint project from the two rappers in the near future? Both are two of the hottest artists in the city, and with similar fan bases it would only make sense for them to put a mixape project together.

With all the time they've spent on the road together, they've definitely had the opportunity to make it happen.

Check out the clip, above.
