Megan Fox and Machine Gun Kelly have been in an on-off relationship for quite some time but finally called it quits last year, but the pair recently welcomed their first child together

MGK shared the inspiration for their daughter's unique name just days after officially announcing the moniker to the world in a heartwarming video.

MGK called his newborn "the ultimate gift." Megan Fox and Machine Gun Kelly just revealed the name of their newborn daughter. The couple, who split last fall, welcomed their first child in March. Fox also has three sons from her previous marriage to Brian Austin Green.
