French Stewart is a dad! The actor and his wife Vanessa welcomed a baby girl.

Helene Claire was born six weeks early, at 7 in the morning on Friday, June 28. The parents chose family names for their newborn, with two Helenes in Stewart’s family and five Claires among Vanessa’s.

Best known for his role as Harry Solomon in 3rd Rock From the Sun, 49-year-old Stewart has appeared in StargateLove Stinks, and Inspector Gadget 2, and has recently played roles on TV shows including The Middle, Psych, and Community.

But despite his latest role as a dad, Stewart also has Mom on the mind, the CBS comedy starring Anna Faris, Matt Hones, and Allison Janney. “In the daytime I work on a special new show [Mom] with wonderful people. And at night I have new adventures with Vanessa and Helene,” Stewart told People.

The new series airs on CBS Sept. 23.
