Former New York Giants star Tiki Barber and fiancée Traci Lynn Johnson have postponed their May wedding in the Hamptons because Barber’s divorce from estranged wife Ginny won’t be finalized in time.

Sources say Tiki and Traci were due to marry May 12 at the Sag Harbor home of EMM Group co-founder Eugene Remm, whose nightlife and hospitality firm’s holdings include New York hot spots Abe & Arthur’s, SL and Tenjune. The couple had hoped Barber’s divorce from Ginny Cha would be finalized by then, and Johnson’s friends last month threw her a wedding shower.

Earlier this month, Barber reached a divorce settlement with Ginny after two years of bitter wrangling over child support and alimony. But a source told us, “The divorce will not be finalized in time for the May 12 wedding, so Tiki and Traci have told friends and vendors that the date will be pushed back to, hopefully, early summer.”

Ginny and Tiki had been married 11 years when they split in March 2010, when Ginny was eight months pregnant with twin girls. Tiki, who at the time was an NBC Sports and “Today” show contributor, left her for Johnson, a former NBC intern. Ginny filed for divorce in April 2010, and Tiki and Traci became engaged last year.

Tiki, who retired from the New York Giants in 2006, had at one point claimed during their divorce proceedings that he couldn’t afford to meet Ginny’s demands for alimony and child support. In addition to their twin girls, born in May 2010, the couple have sons AJ and Chason.

Barber attempted an NFL comeback last year, but no teams signed the 37-year-old running back.

A lawyer for Ginny told The Post in early April only that the matter was “settled,” while a lawyer for Tiki did not return a request for comment.

Both sides refused to say exactly what Ginny got in the agreement, although it was likely to be less than the $150,000 a month in alimony that sources said she demanded after the pair split.

Remm declined to comment on the wedding, and Barber didn’t get back to us.
