Jaden Smith may have just won the award for craziest accessory at the Grammys … pulling up early to the ceremony with a huge castle hat.

The rapper hit the event with his sister Willow — who wore just underwear beneath a black coat … and, he donned a large black castle atop his head, with his face appearing in the structure’s door.

It’s sorta hard to describe, so make sure you check out the pictures for yourself … it’s a bold fashion choice — though the person sitting behind him at tonight’s festivities may not appreciate the look.

it might be high fashion, but it’s not getting a lot of love online … ’cause many are questioning Jaden’s sanity after this fashion choice. One person even says he’s dressed like a villain from Batman’s rogues gallery.

While the Grammy Awards is a place for music’s biggest stars to show off their strangest fashion — just ask Bianca Censori who stripped naked on the red carpet before the ceremony — Jaden’s house has to be one of the strangest style choices in the show’s history.

Jaden’s not up for an award tonight — his only Grammy nod came in the Album of the Year category for “Justice” back in 2022 — but, his dad Will Smith is presenting … a big moment given he’s been a bit of a pariah since slapping Chris Rock at the Oscars in 2022.
