Steve Schwarzman (pictured)won’t let anything get in the way of a good time at the multiplex. To see “It’s Complicated” over the holidays in West Palm Beach, the Blackstone billionaire had an aide hold two seats in the middle of the theater for him and his wife, Christine. “The assistant was shooing people away until Christine and Steve got there,” says a spy, “at which point she gave the seats to them and left.” Christine came toting popcorn in an Hermes shopping bag. Checking out “Avatar” in a different theater were Donald Trump and Regis Philbin.
