Lohan said she was "lucky and blessed" to be able to act.

"I've been acting my whole life and this is what I love to do," said Lohan, who stars in the upcoming "Bobby," about the 1968 assassination of Sen. Robert F. Kennedy.

Lindsay recently told In Style magazine that by age 30 she wants to find true love, have a house to call home, and win an Oscar. Lindsay admits she said those things, but in a casual manner. "I'd like to. I don't hope for everything-I'm setting extreme standards for myself," she says.

Emilio Estevez, who directed the movie, told Winfrey that Lohan was a professional on the set, showed up on time and turned in "the best work of her life."

The media focuses on allegations of wild-child behavior "because it sells," Estevez said. "I'd rather have them focus on how extraordinary she is in this film," he said.

"Bobby," set for release Nov. 23, has an ensemble cast that also includes Demi Moore, Sharon Stone, Anthony Hopkins and Laurence Fishburne.
