Machine Gun Kelly was accompanied by one of the leading ladies of his life at the 2021 American Music Awards, and no, it wasn't Megan Fox.

The rocker, 31, made a rare red carpet appearance with his 12-year-old daughter Casie Colson Baker as the duo posed for the cameras together.

The 'Rap Devil' singer, whose real name is Colson Baker, arrived on the red carpet at the AMAs on Sunday in a custom bedazzled Ashton Michael outfit, while his daughter Casie wore a floor-length black gown.

During the rare father-daughter outing, the singer locked hands with his daughter, who he shares with ex Emma Cannon.

At one point, the pair were photographed locking pinky fingers and kissing their thumbs in what appeared to be a secret handshake.

MGK later earned the award for Favourite Rock Artist, with the singer telling the audience that he wanted to accept the award for "all the aspiring musicians, the one that wants to play an instrument, wants to rap, wants to see - not just the rock artists, but the artists who are rock stars".

He added: "Lastly, I just wanna say this: I read a headline that says the age of the rockstar is dead, but looks pretty alive to me!"

Machine Gun Kelly posted a series of snaps from the awards show to Instagram, and captioned the pictures: "tWINning," alongside a black heart emoji.

Casie has attended a number of shows with the rapper in the past, including the Nickelodeon Kids' Choice Awards, and MGK often shares pictures of her on social media.

While MGK's girlfriend Megan Fox wasn't in attendance, the actress has already racked up plenty of memorable red carpet appearances with her boyfriend of over a year.

The Jennifer's Body star also has children from a previous relationship, sharing sons Noah, nine, Bodhi, seven, and Journey, five, with ex-husband Brian Austin Green.

MGK and Megan sparked up a romance in May 2020, after meeting him on the set of the movie Midnight in the Switchgrass shortly after her separation from Brian.

It seems that Megan wants to have more children with MGK, as she and Kourtney Kardashian referred to him and Travis Barker respectively as their "future baby daddies" at the VMAs earlier this year.
