Rose Namajunas may be knocking opponents out as an adult, but as a kid she was killing folks with cuteness.

The strawweight contender posted this photo to Instagram on Friday, showing off her skills as a children's clothing model.

Namajunas has won her last two fights inside the Octagon by submission, including a dominant performance against Paige VanZant at UFC Fight Night in Vegas where she outstruck her opponent 57-10, landed a career-high eight takedowns before finishing the fight in the fifth round.

As one commenter said, "sell 'em pajamas before you put 'em to sleep." True, indeed.
