Usher's roller skating skills are so, so def ... and here's proof!
Usher hit up Jermaine Dupri's "Picture Me Rolling" Thursday night in the ATL. The shindig was a private event hosted by Jermaine, who rented out Cascade skating rink.

Jermaine made sure the full kitchen was available for those hungry after working up a sweat ... and for the adults -- open bar!!
