Lindsay Lohan’s father, Michael, is “very upset” with the crowd his daughter has been hanging with in New York, and insists there “will be changes.” After Lohan finished shooting Bret Easton Ellis’ movie “The Canyons” in LA, she’d been in a series of Big Apple disasters, from a W Hotel dust-up with a Congressional aide to an alleged fight with mother Dina after partying till the wee hours in Chelsea. Michael says it’s the crowd surrounding Lindsay in New York that’s the bad influence, and he wants her to get back to focusing on her career. “I am very upset with the crowd around Lindsay,” he told Page Six in an e-mail, targeting one pal in particular. He also warned Lindsay’s pals, “My advice to ALL the negative influences in Lindsay and my other children’s lives is, this time, you have crossed the line and bitten off a lot more than you can chew! My family will not be subject to your misguided morals and ways!” Michael also vowed that things will change in his daughter’s life. “There WILL BE changes!! Just watch,” he wrote.
