Every star in the league cries to refs now. They get too spoiled, getting foul calls for other people breathing on them (especially in the reg. season.) Once they get to the playoffs and the refs let teams actually play basketball they get all pissy when they don't get the same calls they got months ago.
Wade and Bron are some of the worst at it. Pierce is usually pretty bad too, lets not forget the wheelchair. Most stars do this though, its rare an NBA star isn't a cry baby to refs. They know it works after you keep bugging a ref (due to their influence), so they still do it.
