"America's Got Talent" judge Sofia Vergara joked that she sometimes feels insecure around her fellow judge Heidi Klum. The 50-year-old actress talked about comparing herself to Klum, 49, in an interview with Fox News Digital after the talent competition show's season 17 finale on Wednesday night. "I mean, Heidi Klum, have you seen her? It's like, God, she's a supermodel!" Vergara exclaimed while on the red carpet at the Sheraton Pasadena Hotel in Pasadena, California.
