Machine Gun Kelly's only child, Casie, was born on July 23, 2009. Casie shares her middle name, Colson, with her dad. The father-daughter duo don't appear in public photos together all that often, but their strong bond is apparent. In a 2019 tweet, MGK wrote, "two connecting flights and still no sleep but ima make it to my daughter's recital tonight believe that !!"
On Casie's 11th birthday, her dad shared a gallery of photos of the pair captioned: "the princess turned 11. 🥰👑🎂🖤 dassss my best friendddd."
In addition to being an adorable parent-kid duo, Casie and her dad are also working together! On Feb. 11, the singer and actor shared an Instagram gallery captioned, "our first movie together," which included a video and photos from the set of One Way, a thriller releasing in 2022. A few days prior, MGK tweeted, "my daughter is in this movie with me and i just saw her name on the press release ima proud dad."
