One half of City Girls may be behind bars, but it hasn't stopped the duo from keeping their momentum going. While JT does time for charges related to felony identity theft, Yung Miami is teasing new music from the duo, and it seems she's secured a collaboration with 21 Savage next.

A new post from the City Girls Instagram account sees Miami posing with 21 with an instruction to "stay tuned" for a potential collaboration. It is unclear if this would be an official City Girls collaboration or one solely between Miami and 21 but it's an exciting prospect either way. 

As you likely know, City Girls are already a part of a Hot 100 No. 1 hit, due to their additional vocals on Drake's "In My Feelings." Their excellent debut PERIOD was released in May through Quality Control. The South Florida duo very recently released the video for the title track. Watch it here.

As for 21, the rapper recently revealed he had been working with Childish Gambino and Pharrell on new material. His tweet about a "Savage Summer" from earlier this year had fans speculating that his follow-up to Issa Album could be on the way, but there's yet to be an update.
