MGk.

Jelly Roll made time for some more earthly pleasures: cameos from BigXthaPlug and Wiz Khalifa that reminded you of his hip-hop roots, and an appearance by MGK, who did his appealingly bratty pop-punk “My Ex’s Best Friend.”

Representatives for Fox and MGK, whose real name is Colson Baker, did not respond immediately Thursday to requests for confirmation and more information.

“She just wants to focus on the baby and her boys now. She lives alone and doesn’t have much contact with MGK.”

Fox’s romance with MGK has been the subject of much speculation amid recent reports of growing conflict between the two.

This season I have learned numerous useful things — like why you shouldn’t tell the guy you’re dating through a wall that you look like “MGK’s girlfriend” unless you are, in fact, Megan Fox; the dangers of eating too many piping hot taquitos from a beachfront buffet and being unable to kiss your fiance as a result; and the fact that Charlotte, N.C., has some of the most soulless corporate housing the world has ever seen.
