Kira Kosarin Body Measurements, Height, Weight, Husband & Net Worth
Kira Kosarin has spent much of her life in front of an audience. She became a familiar face to Nickelodeon viewers as Phoebe Thunderman on The Thundermans, but her career has since expanded into music, producing, and other television projects.
She once posted two photographs of herself side-by-side, wearing the same swimsuit. In one she weighed 126 pounds; in the other, 136. Her point was that her body had changed, but she was still the same person in both. The post became one of the most recognizable examples of her approach to body image and online criticism.
Kira Nicole Kosarin was born in Morristown, New Jersey, and grew up in Boca Raton, Florida. Both her parents came from Broadway. Her father, Danny Kosarin, is a music director, conductor, and record producer, and her mother, Lauren Kosarin, was an actress.
She began dancing at a young age, trained in ballet at Boca Ballet Theatre, and was dancing full-time by the age of nine. In 2011, her family moved to Los Angeles to support her acting ambitions. Within a year, she had her first television credit on the Disney Channel’s Shake It Up. By fifteen, she was cast as Phoebe Thunderman, a role that defined the first major chapter of her career.
