Sylvester Stallone has given up trying to keep his children grounded, confessing he's treated them to an unbelievably privileged upbringing. The Rocky and Rambo star claims his three kids with third wife Jennifer Flavin are so spoiled, they treat hotels like their homes. He says, "They know they're not normal. They come home to a house the size of a hotel - and have nannies and bodyguards. They get on a public jet and say: 'What are these people doing on our plane?' "We were living in the Peninsula Hotel in Beverly Hills when my second child was born. The eldest thought it was her house. She thought we had 200 staff and the lobby was her living room. She began asking people to leave."
