'Tis the season! Meghan Trainor covered Justin Bieber's Christmas song 'Mistletoe' for German radio show 1LIVE, and she even got props from the singer himself! You can check out Justin's tweet (along with Meghan's sick cover) above!

Meghan's cover is a more stripped down version of the holiday favorite, as it's just a ukelele and an acoustic guitar. Her vocals are the real focus and she does a fantastic job -- not that we expected any less. Our favorite part? When Meghan smoothly transitions right into Jason Mraz's 'I'm Yours,' and then just as expertly switches back to 'Mistletoe.'

Between getting love from Justin Bieber and her recent talks with Harry Styles (oh, did you not hear about that? Apparently the two might be teaming up to write a couple tunes -- well, that's what we inferred from Meghan's tight-lipped interview, anyway!), we are eternally jealous.

What do you guys think of Meghan's cover? Listen above and let us know!
