Tiki Barber has fumbled again.
The ex-Giants star came clean to his unsuspecting wife late last year, admitting he was starting to shack up with a much younger blonde, sources said yesterday.
But Ginny Barber was “devastated” to learn Tiki began his torrid affair with temptress Traci Lynn Johnson much earlier in their marriage — and long before she became pregnant with twins.
“She had no idea what was going on. She had no idea about this relationship with Traci Johnson until he left in late November,” one source close to the Barber family said. “There were no [apparent] problems in the marriage.
“Ginny is devastated by this. All of this came out of the blue for Ginny. People may say, ‘How could she not know?’ But she really didn’t. Tiki is a guy who travels a lot.”
The Post yesterday revealed that Tiki began bedding Johnson as early as 2008, when she was a 21-year-old student at Mount St. Mary College, a Catholic school in upstate Newburgh.
Sources said the dapper running back lavished her with roses, jewelry and designer clothes — and that Johnson was not shy about publicly reveling in her illicit relationship with the married man.
Last Sept. 5 — at around the same time Ginny became pregnant with twins by Barber — Johnson posted a photo of Barber’s blue Maserati on Facebook, and called it her “Boyfriend’s whip” — slang for car.
Barber bought that exotic car in 2003, according to a Web posting by Maserati, which noted at the time, “Tiki is considered a model athlete, not only for his athletics, but for his clean living lifestyle.”
Sources told The Post yesterday that Tiki’s lucrative contract with NBC’s “Today” show — whose 10 a.m. hosts Hoda Kotb and Kathie Lee Gifford talked about the scandal yesterday — could soon end.
An NBC source said, “Barber signed with NBC for a lot of money, up to $2 million, which is a great deal more money than their other correspondents earn.
“But he proved to be a disappointment on screen, and he has recently been used less and less. His contract is up for renewal soon, and this is a good excuse to get rid of him.”
A “Today” rep refused to comment, but a source said, “Tiki Barber is currently a ‘Today’ show contributor.”
Barber’s agent, Mark Lepselter said, “Tiki has a contract with NBC, and I’ve heard nothing to the contrary.”
Lepselter also said that Barber — who in the past has fumed about how his dad abandoned him and his twin brother Ronde as kids– “hasn’t abandoned his family.”
“This guy is a very active father,” Lepselter said, noting that Barber spent his 35th birthday Wednesday playing sports with his and Ginny’s two sons, A.J., 7, and Chason, 6.
