Machine Gun Kelly is giving the people what they want — finally dropping the name of his baby girl with ex Megan Fox … and as you’d expect, it’s not your average playground pick.

In a Tuesday IG vid, MGK gave fans a tender daddy-daughter moment — strumming a soft tune on his ukulele while his baby girl (mostly out of frame) listened in — but the real showstopper was the caption: “Saga Blade Fox-Baker .”

MGK was definitely all kinds of proud with the bold name choice — and he even shut off comments on the post … ‘cause when you name your kid Saga Blade, you don’t need anyone else’s two cents.

As you’ll recall, Megan welcomed her fourth baby — her first with MGK —  back in March. He broke the news with a black-and-white shot of their daughter clutching his finger.
