Earlier this week, Cardi B returned from her brief Instagram retirement to announce that she was linking back up with Bruno Mars for a new single. Now, the track is here in its entirety. It's called "Please Me," and you can hear it below. Last winter, the two teamed up for the "Finesse" remix. Cardi was due to open for Bruno on his 24K Magic Tour last summer, but pulled out on account of her pregnancy.
