Machine Gun Kelly and Megan Fox's Relationship Drama
Machine Gun Kelly fought back in concert after Megan Fox blocked him on Instagram.
The sweet gesture of performing the song on her birthday comes after the on-off couple traded barbs online.
During his Wednesday, April 8, concert, in Perth, Australia, MGK sang his and The Kid Laroi's duet "F--- YOU, GOODBYE," a song that wasn't a staple on his setlist.
"I’m definitely not the one to give relationship advice, but if I was to give any, I’d say if you gotta call up your ex, probably tell 'em this..." the musician announced before the lyrics, "F--- you, goodbye/ You hurt me for the last time," played over the speakers.
The dig came shortly after Fox appeared to block MGK on Instagram when he made a few flirty comments on her racy photos.
