VIDEO: Bill O'Reilly Grills Barbara Walters About Fascinating People List

"Stop giving me a hard time, Billy!" she snaps after he questions if she asked Sarah Palin about her sexuality.

Bill O'Reilly grilled Barbara Walters about her picks for her annual Fascinating People List, which she announced on ABC Thursday night.

In an appearance on The O'Reilly Factor that also aired Thursday, O'Reilly said he didn't think the Jersey Shore cast deserved to make the list. Walters shot back that they were the most successful reality show in MTV history.

O'Reilly said, "It's not that they're fascinating. It's just that they get a lot of press."

O'Reilly also said he didn't agree with her decision to ask Oprah Winfrey if she was a lesbian given her close friendship with Gayle King. "I wish that you and all the other celebrity interviewers wouldn't ask these kinds of questions," he said.

Snapped back Walters, "You think I'm a celebrity interviewer? Is that all I am?"

"No," said O'Reilly, "I think you're a journalist, but you do a lot of celebrity interviews."

"So do you!" shot back Walters. O'Reilly shrugged her off, "We don't have a lot of these pinheads on any more because they don't have anything to say."

O'Reilly also asked Walters if she asked Sarah Palin -- whom he referred to her as her "token conservative" on her most fascinating list -- if she was a lesbian.

"It wasn't pertinent!" Walters said. "Stop giving me a hard time, Billy."

At the end, O'Reilly changed his tone and told Walters, "Thanks for taking all my nonsense." She told him she loved him.

O'Reilly infamously feuded with Walters and The View co-hosts earlier this year about the 9/11 mosque.
