The 34-year-old Transformers star couldn't control herself when her boyfriend hit the stage to perform in Jacksonville, Florida over the weekend.
Wearing a crop top and black pants, Megan Fox was spotted dancing and singing along to Machine Gun Kelly from the front row. Flashing her gorgeous smile, the brunette bombshell glowed while making eye contact with her man onstage.
Jumping up and down with fans surrounding her, Megan Fox looked like she was having the time of her life and it was all captured on video.
"When Megan Fox sits right behind you to watch her man," one concertgoer wrote on the video which was shared on Chicks In The Office's Instagram.
Fans of the couple immediately reacted to the swoon-worthy footage. "Megan was made for this," one person wrote. "Goes to MGK concerts strictly for Megan Fox," joked another. "OMG SHES IN LOVE," added a third.
Following the concert, the couple was seen packing on the PDA backstage. In an Instagram Story, shared on Megan Fox's page, the actress was seen leaping into MGK's arms and showering the rapper with kisses.
The duo was later photographed holding hands while attending the UFC 261 fight.
The Jennifer Body's star's epic fangirl video comes as engagement rumors are swirling about the couple. According to E! News, Machine Gun Kelly plans on popping the question as soon as her divorce with Beverly Hills, 90210 alum Brian Austin Green is finalized.
They "plan to get engaged and married," the insider told the outlet. "They are very much in love and have a strong and intense relationship," the source added. "Her divorce is moving along, and they are hashing out custody details."
Their weekend full of PDA also comes after the Bloody Valentine rapper was caught leaving a club with a mystery woman. Machine Gun Kelly made eyebrows raise when he was photographed exiting a hot nightclub with a blonde who was trailing behind.
Turns out, it was just his assistant, who seemed to really enjoy all the attention.
