Jaden Smith — Multi-Million $$$ Pay Out for ‘Karate Kid’

Tmz :    He’s only 12 years old — but last year, Jaden Smith pulled in SEVEN FIGURES to star in “Karate Kid” … TMZ has learned.

TMZ obtained Jaden’s “KK” contract from June 2009 — back when he was only 10 — and according to the docs, his up-front fee was split into two installments … one for $900,000 and one for $100,000.

But Jaden’s back end deal was even more lucrative — since the film topped $150 million in the domestic box office, the young actor locked down another $2 million bonus.
