This week on Under the Radar with Callie Crossley:

You probably recognize the work of actor and producer Sarah Jessica Parker, basketball phenom Dwyane Wade, queen of hip-hop soul Mary J. Blige, actor Cameron Diaz and singer-songwriter John Legend. And maybe you know these stars of film, TV, music and sports are running a flavorful side hustle. They are a handful of celebrities who’ve started producing and selling their own wine.

We’re sipping with the stars as part of our Summer Fun Series.
