HEF’S KEEPING HIS EXES CLOSE

HUGH Hefner doesn’t mind that many of his girlfriends have moved on with other men – to a point. “Contrary to reports, I’m still planning on walking Kendra [Wilkinson] down the aisle when she gets married this summer [to NFLer Hank Baskett] at the Mansion,” the Playboy founder and subject of the new bio, “Mr. Playboy: Hugh Hefner and the American Dream,” tells Page Six. But while Kendra and another ex, Holly Madison, will appear on the sixth season of Hef’s reality show, “Girls Next Door,” don’t expect much screen time for Baskett or Madison’s paramour, Criss Angel.“I’ve still got to figure that out,” he says.
