Megan Fox is featured on boyfriend Machine Gun Kelly's new album

Megan Fox and Machine Gun Kelly have taken their relationship to the next level, cementing it in song.

The Transformers actress features on a track off the rapper's newest album Tickets to My Downfall.

Fox's voice can be heard on an interlude titled 'Banyan Tree'. It's a recorded conversation between the couple that lasts for about a minute-and-a-half.

"Oh, my god. Did you drink a lot of tequila? Is that what it was?" Fox can be heard on the track, teasing Kelly. "Do you like, remember the stuff that you do with me? OK, I don't know 'cause you're so high or like, you get really drunk, so I don't know if you remember it."

Kelly responds, "Of course I do. I cherish it. I burn other memories just to make room for those ones. … Because also if the world was coming to an end, I don't wanna close my eyes without feeling like I lived."

The album includes one other interlude, which is a recording of a phone call with Kelly's close friend, actor Pete Davidson.

Kelly and Fox began dating earlier this year, though it was only confirmed in June. The pair met while working on a movie together in Puerto Rico.

Up until late 2019, Fox was married to actor Brian Austin Green – the couple shares three sons.

Earlier this week, Kelly revealed that he basically fell in love with Fox at first sight. "I didn't know what [love] was until me and her made eye contact," he said. "That's when I was like, 'whoa.'"

"That was my first experience with being open to love and stuff like that. I definitely wasn't set up to believe that that's something that could ever exist."
