Machine Gun Kelly and Megan Fox welcomed their daughter into the world in March and finally revealed the child's name.

The Tickets to My Downfall rapper posted a video of him serenading their newest bundle of joy on Tuesday (June 17) and shared her name in the caption.

"Saga Blade Fox-Baker," Kelly, born Colson Baker, wrote aside a fiery heart. The artist also thanked Fox for "the ultimate gift."

In the clip, Kelly played his ukulele for the two-month-old who seemed to be enjoying the tune as she kicked back and forth in her seat.

The Jennifer's Body actress ended things with Kelly in November 2024 after discovering content on his phone that she found unsettling, which ultimately led her to cut off their connection. In April, an insider told People that Kelly and Fox are "getting along" post-breakup and that they're excited to be parents again.

"Megan and MGK are really loving this time right now with their baby girl. They're not making any big decisions about their future together as a couple because they just want to focus on the present and this new chapter as parents to their daughter together."

Baby Saga is not Fox's nor Kelly's first child. Fox shares sons Noah, 12, Bodhi, 11, and Journey, 8, with ex Brian Austin Green, per People, and Kelly shares Cassie, 15, with ex Emma Cannon.
