Simon Helberg and his wife Jocelyn Towne have confirmed that they are expanding their family. The actor, who is best known for playing Howard Wolowitz in The Big Bang Theory, confirmed the news at the Screen Actors Guild Awards after his other half showed off her baby bump on the red carpet. “Yes, my wife is (pregnant)... I can’t take all the credit,” he told Entertainment Tonight before adding that it was this time two years ago that they were expecting their first child. “Every time I come to the SAG Awards there’s always something about this night... About eight months before I get really the urge, I feel the romance and then we get nominated so it’s hand in hand.” The star couple, who walked down the aisle back in 2007, already have a one-year-old daughter called Adeline. Simon and Jocelyn are expecting their second child together.
