Well, hopefully, Wynonna and Naomi Judd will have folks pushing their shopping buggies down the aisles. The twosome, who've also planned a New Year 2000 reunion concert, announced at a recent Music City press conference that they will become on-air spokespersons for new Kmart commercials. The Judds will replace Hollywood stars Penny Marshall and Rosie O'Donnell. The marketing venture between the popular chain of stores and one of music's most prominent duos will run its course throughout the next couple of years.
