With his “Iron Man” suit, Jaden Smith has outdone Justin Bieber in crazy costumes.

Wednesday saw the 14-year-old in New York City with his rumoured girlfriend Kylie Jenner. Jenner, 15, wore a sleeveless leopard print dress to deal with the New York heat, while Smith wore a mask and red and gold jumpsuit resembling Robert Downey Jr.’s “Iron Man” suit.

Smith bought the costume earlier in the day and wore it to lunch at Nobu, according to the Daily Mail.

Smith was in town to promote his new film “After Earth,” which co-stars his father Will Smith. Jenner seemed excited to support her rumoured boyfriend, even though the elder Smith had recently spoken poorly of her family.

Reality star shared friend’s post, “Can’t wait for #AfterEarth’s New York premiere tonight! Kylie Jenner So proud of @officialjaden, scopes.”

It’s unclear why Jaden wore the “Iron Man” outfit, but he at least ditched it for the premiere on Wednesday night.
