• Machine Gun Kelly confirmed that Megan Fox is his girlfriend in a tweet on Monday.
• Speculations of a romance between the actress and musician ramped up after Fox starred in Kelly's music video for the song "Bloody Valentine."
• "i'm calling you girlfriend what the f---," Kelly wrote, quoting "Bloody Valentine" lyrics. He added, "life imitated art on that one."

Megan Fox and Machine Gun Kelly are officially dating, the musician confirmed in a tweet on Monday.

They ignited romance rumors in May after Kelly, whose real name is Colson Baker, released an intimate music video for his song "Bloody Valentine" featuring the "Transformers" actress.

In a tweet on Monday, Kelly quoted lyrics from the song, using them to publicly confirm his relationship with Fox.

"i'm calling you girlfriend, what the f---," he wrote, adding, "life imitated art on that one."

Shortly before the "Bad Things" singer confirmed their relationship on Twitter, Fox and Kelly held hands and kissed while leaving a bar in Los Angeles together on Monday evening, as seen in photos published by the Daily Mail.

The couple met while filming "Midnight in the Switchgrass" in Puerto Rico before production was halted due to the coronavirus pandemic. They were also spotted getting takeout together in Los Angeles days before the "Bloody Valentine" video was released.

Brian Austin Green, who was married to Fox for 10 years, announced that they'd been separated since the end of 2019 on his podcast "...With Brian Austin Green" on May 18. They have three children together: Noah, 7, Bodhi, 6, and Journey, 3.

The "Beverly Hills, 90210" actor said he will "always love" Fox and called her his "best friend" before addressing rumors that she'd moved on with Kelly, who Green said he'd never met.

"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. I trust her judgment. She's always had really good judgment," he said.

Green continued, "I don't want people to think that her or he are villains or I was a victim in any way with any of this — because I wasn't. This isn't something new for us. This is something new for people to experience and hear about in the press, but it's not new for us."

Fox and Green, who met on the set of "Hope & Faith" in 2004, have gone through several breakups and subsequent reconciliations.

In 2009, they called off their engagement before getting back together and exchanging vows in 2010. And in 2015, the "Jennifer's Body" actress filed for divorce, citing irreconcilable differences, but ended up staying with Green.

On Monday, Green was seen spending time with Courtney Stodden in Agoura Hills, California. E! News reported that Green was "very attentive to her" and "opened the door for her when she got in the car," according to an eyewitness.

Neither Green nor Stodden, however, have confirmed the relationship.
