The two have teamed up to release the song Leave The Door Open under the supergroup moniker of Silk Sonic.
Mars and Paak, both 35, took to the stage early in the evening to perform their tune, a love letter to the soul music of the 1970s.
They both performed in retro-style dark orange suits and the performance featured a trio of backup singers in traditional 70s. style.
