Actress Kari Byron and husband Paul Urich have welcomed their first child, a daughter - Stella Ruby.

According to her Mythbusters costar Grant Imahara’s twitter message, Stella Ruby was born June 28 at 11:35pm after 42 hours of labor, weighing 8lbs., 12oz. He goes on to say that both Kari and baby are in good health.

Kari, 34, who announced her pregnancy in February saying “That's right, I'm busting myths for two now", admitted there were some challenges working on the show while pregnant. “If I drop a screwdriver and try to pick it up, sometimes I need help getting back up myself. She also “made a 'Costanza' under [her] desk… to take naps when no one is looking.”
