New York: Legendary actress Betty White has said that Charlie Sheen and Lindsay Lohan are ``ungrateful`` actors who cannot appreciate their fame.
"I cannot stand the people who get wonderful starts in show business, and who abuse it," the New York Daily News quoted White as telling the Daily Mail.
"Lindsay Lohan and Charlie Sheen, for example, although there are plenty of others, too. They are the most blessed people in the world and they don``t appreciate it.
"They party too much, don``t learn their lines, are unprofessional and they grumble about everything. I think they are terribly ungrateful," the 89-year-old said.
The "Hot in Cleveland" star also gave some advice as well.
The biggest key: "Respect your profession."
"There is an enormous population out there, who would sell their souls to do what you do. It`s an amazing life, so make sure you appreciate every minute of it," she said.
