Yup, he literally posed at the swanky fashion extravaganza clutching the old dreadlocks his dad Will Smith recently hacked off for him.
So what was it all about? Jaden explained his, err, unique look to US Vogue's André Leon: "I've gone for the Dracula look today. And since I couldn't bring my sister as a date, I brought my old hair."
Say what?! Not sure if Willow Smith will be touched or creeped out. Can your hair really replace your SISTER?!
Anyway, Jaden also revealed that his blinged-up grills weren't just gold, they had diamonds too! "This is for the evening only," he said. It has diamonds in it too."
"Jaden Smith. The grill of golden diamonds! Future legend and icon at the Met. #legend2032"
Oh, and here's Jaden dancing with his dreads.
