Kelsey and Kayte, who plan to call their son James, named him after their favorite influential men, poet W.H. Auden and singer James Taylor. As for Ellis, that's Kelsey's great grandfather's name on his mother's side. "He was a colorful character to say the least and we wanted to give the name a second chance," the actor says.
This is the third child for Kelsey and Kayte, who share 4-year-old daughter, Faith, and 2-year-old son, Kelsey Gabriel. Kelsey also has four other children -- Spencer, 33, Greer, 24, Mason, 15, and Jude, 12 -- from previous marriages.
ET spoke with Greer last month, and she had some advice for her seventh sibling. "I would tell them to focus," she said. "In school, I kind of did the lazy overachiever sort of thing up until college. In college I tried a little bit harder, but I think it's really important to do that starting at a young age."
Greer, who's mother is hair and makeup stylist Barrie Buckner, also gushed over how great Kelsey and Kayte are at being parents. "They have so much fun having the little kids running around the house," she explained. "It's so exciting. They're just so happy, and my dad always wanted a really big family, so it's just cool."
