More than 10 million people watched local guy Donnie Wahlberg enjoy his girlfriend, Jenny McCarthy, on “Dick Clark’s New Year’s Rockin’ Eve” on ABC. The two have been dating since March, when the New Kid appeared on her VH1 show. Not long before the ball dropped in Times Square, Donnie posted another teaser for his new reality show, “Wahlburgers,” which premieres on A&E on Jan. 22. The clip shows him and Mark Wahlberg play-fighting with their brother Paul, who’s the chef at the Hingham-based burger joint.
