REPORT: WILL SMITH IS CAUSING PROBLEMS ON THE SET OF JADA PINKETT'S NEW SHOW!!!

"He is not currently shooting a movie, so he's been a constant on the set in recent weeks," the network source says. "He's been inserting his input and requesting so many changes to the script that it pushed back the production schedule tremendously and caused everything to spiral out of control."

Pinkett Smith plays a nurse on the hit show, which premiered last year to stellar ratings. But despite the first season's success, our insider says her husband wants the dramatic scenes pushed to the limit - and he apparently submits pages of notes and rewrite requests to the show's writers and producers each week.
