Jason Derulo and Jena Frumes are proud parents! Nearly one month after she gave birth to little Jason King, Jena was seen cradling the adorable newborn on June 3 in Los Angeles — see the pics here. The 26-year-old model was photographed on what appeared to be on the set of a photoshoot with her mini-me son, four weeks after she and the 31-year-old musician welcomed him into the world.
