The 30-year-old and ex Emma Cannon welcomed daughter Casie in 2008, and he's since had a star-studded list of exes. Most recently, he's been linked to New Girl actress Megan Fox, who was married to Brian Austin Green until 2020.
Read on for the refresher on Machine Gun Kelly's girlfriend list.
1. Megan Fox
While the two have yet to confirm the rumors themselves, Megan appeared in MGK's music video for "Bloody Valentine," which dropped on May 20, and things were steamy between them, to say the least. Several days before the music video came out, Megan's estranged husband, Brian Austin Green, confirmed that the two had decided to part ways after three kids and nearly 10 years of marriage.
He also said on his podcast With Brian Austin Green that his ex and the rapper were just friends, despite contrary rumors.
"I've never met him, but Megan and I talked about him and they're friends at this point. And from what she's expressed, he's a really just nice, genuine guy," he said. "I trust her judgment. She's always had really good judgment."
According to reports, Megan and MGK originally met when they filmed the upcoming thriller Midnight in the Switchgrass. They've since been spending time together during quarantine, when Megan's three sons are with their dad.
"They have been spending time together at Megan's house in the past few weeks. They seem to have fun and look happy together," a source told People. "Megan only sees him when the kids are with Brian."
2. Sommer Ray
MGK and the fitness influencer went public with their romance in March of 2020, but their relationship didn't last for long after that.
On April 22, Machine Gun Kelly tweeted that Sommer had removed her belongings from his house on his 30th birthday.
"She came and picked all her stuff up on my birthday," he wrote. "Nice."
After Sommer began getting backlash online, the "Bad Things" rapper followed up on his original tweet and said that his ex was "a great human."
"I shouldn't have tweeted personal business," he tweeted. "Especially when the person is a great human and this tweet seems one-sided."
3. Noah Cyrus
MGK and the "NC-17" artist were seen getting cozy at several afterparties for the 2020 Grammy Awards. Just a few weeks before the music awards, he was linked to best friend Pete Davidson's ex, Kate Beckinsale, after they were seen leaving a Golden Globe Awards after party.
Though Noah and Machine Gun Kelly took photos together and were seen holding hands, it seems as if that was the extent of their romance.
4. Chantal Jeffries
The King of Staten Island actor was linked to the D.J. in the summer of 2019 after they were spotted several times out in public together. But, they never confirmed that they were officially dating and their last public appearance was at the end of the summer.
The "Graveyard" singer was linked to Machine Gun Kelly in 2017 after they met on the set of the Showtime series Roadies. Things did not appear to end well, as he feuded with Halsey's then-boyfriend, rapper G-Eazy, in 2018.
Halsey seemed to reference the conflict between the rappers when she tweeted, "How *absolutely* pathetic," in September of 2018.
6. Amber Rose
Amber and MGK started dating in mid-2015, and it was one of the few romances that the rapper confirmed himself. But, they split by June of that year, and MGK has since stayed fairly mum about his subsequent relationships.
7. Emma Cannon
Not much is known about how long MGK dated Emma for, as she's not a public presence on social media. She gave birth to their child together, Casie Colson Baker, in 2008. Though Machine Gun Kelly sporadically posts photos of Casie on his Instagram page, for the most part, he keeps his daughter offline.
