Alec Baldwin Is Pissed at Diane Sawyer

Alec Baldwin has some serious anger management issues. Alec had agreed to give Diane Sawyer an exclusive interview about his upcoming book "A Promise to Ourselves," but threw a hissy fit when she had to reschedule the interview.

In Diane's defense, she rescheduled the interview because she found out her husband Mike Nichols had to have heart surgery.

"Diane's people couldn't believe how angry Baldwin got," says a source. "She was running back from the hospital!"

Remember how livid he was with his 11-year old daughter when she didn't return his phone calls? This guy is out of control! Will you buy his new book?
