Ooh, girl, keep the flirting to a minimum! Y'all have some singing to do!
In the middle of their joint singing song, Miles took the vocal break to compliment Ari on her adorable onesie, and made the 21-year-old miss her cue!
Miley Cyrus got game, yo!

No need to apologize, Miles! Ariana is pretty much as free as a bird, so flirt away! LOLz!
