Helene Claire was born on June 28. "She was born six weeks early and could be held in the palm of your hand," Stewart told the magazine. "We named her after my lovely mother. My sister is also a Helene. There are five wonderful Claires in Vanessa's family so the tradition of it is very special for us."
Stewart, 49, married Smith, his second wife, in 2011. Famous for his role on 3rd Rock From the Sun, he'll return to TV in the fall on CBS' Mom playing the hot-tempered chef at the restaurant where Anna Faris' Christy works. The comedy debuts on Monday, Sept. 23 at 9:30/8:30c.
