It looks like Kathie Lee Gifford can finally laugh about her hubby’s cheating ways.

The “Today” show co-host mocked Frank Gifford’s infamous philandering Tuesday during a discussion of new claims that he had an affair with Johnny Carson’s wife in the 1970s.

Kathie Lee told co-host Hoda Kotb that such a tryst would be right out of the ex-Giant’s playbook.

“No, it’s not true, that particular one,” she joked about the Carson claims. “Although we all know what the man is capable of.”

Kathie Lee was referring to a 1997 sex scandal in which the legendary New York Giant was caught on videotape fooling around behind her back with a flight attendant.

Kathie Lee jokingly said she grilled him about a new report that he had an affair with Carson’s wife, Joanne — long before Kathie Lee was married to Frank.

“Tell me, it was a long time ago. Did you have an affair with her?” Kathie Lee said she asked Frank. “He goes, ‘I can’t remember! Maybe!’ ”

Kathie Lee was more serious later, when reached by The Post at her Greenwich, Conn., home.

“It’s not true. It was a long time ago and it never happened,” she said.

Frank, a Pro Football Hall of Famer and former “Monday Night Football” TV announcer, has been accused in a new book written by Johnny’s former attorney Henry Bushkin of secretly bedding Carson’s wife.
