LOS ANGELES: Lily Collins is a nightmare to work with. The actress - whose dad is singer Phil Collins - “will completely ignore anyone who isn’t A-list,” a source said. “And at a recent party in Bel Air, she literally threw her cocktail on the carpet because she didn’t like it! Everyone was horrified,” a source said. “One editor cancelled a photo shoot because she heard Lily was terrible to deal with. “She’ll demand to bring her own stylist and is so prissy that she refuses to use a bathroom that’s been used by someone else. Her ego is going to ruin her career if she doesn’t get herself in check!”–SP
