The Big Bang Theory star Simon Helberg has become a dad for the second time.
The actor - who plays Aerospace Engineer Howard Wolowitz in the hugely popular US sitcom - and his wife Jocelyn Towne welcomed their son back in April, but is only now being announced.
A spokesman for the actor confirmed the secret birth and added that the couple have named their child Wilder Towne Helberg. He will be a brother to their daughter Adeline who was born in May 2012.
Helberg previously confirmed his wife's pregnancy after she was pictured at the Screen Actors Guild Awards cradling a baby bump.
The actor joked about the fact his wife has been pregnant at two separate SAG Awards.
"Every time I come to the SAG Awards there's something about this night,” he said.
“About eight months before [the SAG Awards], I really get the urge. I feel the romance and then we get nominated, so it's hand in hand.”
