Megan Fox got slammed into a barricade when a person allegedly tried to attack Machine Gun Kelly Thursday night.

TMZ reports MGK and Fox were enjoying the the Orange County fair in California on July 20 when a fellow fair attendee tried to take a swing at the rapper-turned-punk-rocker.

Viral footage from the altercation shows MGK's bodyguard accidentally barreling into and slamming Fox into a nearby metal barricade as he prevents the alleged attacker from approaching MGK.

After she gets caught up in the scuffle, MGK pulls a visibly stressed Fox away and the pair quickly head off.

MGK and Fox's public outing comes following reports that the pair were on a break earlier this year and had even stopped planning their wedding.

"They are very hot and cold. They have stalled wedding planning to work on their issues," a source told US Weekly in March, calling their relationship "pretty volatile."

Cheating rumors swirled prior to the engaged couple's brief break.

"There has been no third-party interference in this relationship of any kind. That includes, but is not limited to ... actual humans, DMs, AI bots or succubus demons," Fox wrote in a statement on her Instagram amid the speculation.
