Despite being labeled "a sore loser" and "a prick" by Fox News Chief Roger Ailes, Newt Gingrich says things are just fine between him and the man who used to cut his paycheck.

"I talked to him a couple weeks ago. We're fine. We don't have a personality fight," Gingrich said Friday on CNN's "The Situation Room."

According to excerpts of an upcoming biography of Ailes, the media mogul was not pleased with Gingrich's assessment of Fox's coverage during the Republican presidential primary.

Gingrich reiterated that criticism Friday, saying Fox--where he was once a paid contributor--covered him unfairly.

Asked why, he said "I have no idea, but I seemed to make them unhappy."

In the book, however, Ailes rebuffed such criticism.

"Gingrich is a sore loser and if he had won he would have been a sore winner," Ailes said, according to excerpts that were released in this month's Vanity Fair.

"Newt's a prick," Ailes succinctly concluded.

While Gingrich maintained his criticism of the network, he seemed to brush off Ailes' harsh comments.

"Look, Roger's a big boy. He's said lots of things about lots of people in his career. I've been around a long time. I've had lots of different people say things about me," he said.
