Chris Brown left rehab, filmed a video, dropped hints about a collabo with Ariana Grande and was reportedly returning to a facility to continue his treatment since he is doing so well. The ever-busy and seemingly reformed R&B star has a dance card that remains full as he may be collaborating with Usher again.

Usher Raymond shared a snap of himself and Breezy in close quarters -- looks like a car, maybe? -- on his Instagram feed, captioning it in telling fashion: "Yep me & @chrisbrownofficial What happens next....#staytuned #Loyal."

What a tease!

'The Voice' coach, who has returned to his red chair for the new season that kicked off this wek, is certainly a good influence on people with whom he works. He mentored Justin Bieber and was even called in to offer some advice and support during The Biebs' recent dark periods.

Additionally, we don't doubt that on a musical level, a new Usher x Breezy collabo would blow our minds. Will it be for Breezy's album? Usher's? A film? Something else? Is it even a song? We don't know.

Breezy previously featured on Usher's 'My Head.'

Breezy tweeted that he will release his long-gestating 'X' album on May 5, which will be his 25th birthday. The album has had several delays, so let's hope this date sticks. And includes an Usher collabo!
