Don't Check On Me (feat. Justin Bieber & Ink)

This mellow, guitar-driven track finds Chris Brown reflecting on a former girlfriend who is struggling to move on. Don't check on me If we're not together, then it's probably for a reason Every heartbreak has its season It ain't always summer in June The singer has cut his ties with his ex, so he doesn't want her calling him.

Justin Bieber takes the baton on the second verse with a similar message to his former girlfriend. I'm distant 'cause I don't wanna be reached now Won't let the ghosts of our past weigh my future down Bieber's relationship had been a toxic one. Now that he's over it, he doesn't want any reminders of his ex.

The emotionally charged ballad is the fifth in a long line of collaborations between Brown and Bieber, which started with 2011's "Up (Remix)," and "Next 2 You." The pair also worked together on "Actin' Up" and "Ladies Love Me."
