Simon Helberg and wife Jocelyn Towne welcomed their first child into the world on Tuesday, May 8th. Helberg, 31, who is most commonly known as Howard Wolowitz on The Big Bang Theory, and his actress/writer/director wife have chosen to name their daughter Adeline. “The family is thrilled” a source tells Us Weekly. “Simon is excited to be a father—he's been doing his reading.” The couple tied the knot in July 2007, months before announcing that they were expecting. Congrats to the happy couple!
