Chris Brown is wasting no time since his release from jail. The "She Ain't You" singer and pal Justin Bieber shared a sneak peek of their duet on Instagram Monday, captioned, "Studio, me and CB did 1 for the fans."

We are still unclear when or if the song will be released as a single, but fans can hardly wait.

Brown was released on June 2 after 108 days of his 131 day sentence for violating probation.
