Kris Humphries and his mom, Debra, are playing Santa this year for more than their own family members. We’re told they “adopted” two local families for the holidays through Debra’s church, and are helping by donating gifts and meals. “It’s something his family has done for years,” says a source close to Kris. “He and his mom adopted two families in Brooklyn, and they spent last week shopping for them.” The source adds, “Kris went to a Target in New Jersey to buy video games, and they’ve been to toy stores, clothing stores and electronic stores.” We’re told the self-appointed elves also took multiple trips to the Apple store because one of their “adopted” family members hopes to “soon be college-bound.” Kris and Debra also ordered holiday dinners from Fresh Direct that were delivered on Christmas Eve. In addition to spreading seasonal joy with his mom, Kris also did holiday community service for the Nets. But the Humph, meanwhile, got a lump of coal from Avery Johnson: The Nets’ coach recently benched him during the team’s dismal December.
