"They're doing great!" Greer said of Kelsey and his wife, Kayte. "My dad and Kayte I think are in New York again, but they're just so excited."
This will be Kelsey's third child with Kayte. The 61-year-old actor is father to 32-year-old daughter Spencer (with wife Doreen Alderman), Greer (with Barrie Buckner), 14-year-old daughter Mason and 12-year-old son Jude (with ex-wife Camille Grammer), and 4-year-old daughter Faith and 2-year-old son Gabe with Kayte.
According to Greer, a big family's always been the plan.
"My dad's always wanted a huge family. Him and Kayte are such great parents together, and they have all these little ones, and they love them so much," she gushed. "They're the cutest kids, Faith and Gabe. I'm excited for them to have another one, another crazy baby."
While Greer's clearly excited for her father's upcoming visit from the stork, the birds and the bees is a topic she and the Frasier star didn't discuss much.
"He did not [give me the talk]," she confessed. "I think he left that to my mom. He was like, 'That's all you. It's all you.'"
"I feel like it's definitely more of a mom-daughter conversation, just like it's probably a father-son conversation. You stick with probably the same sex parent maybe," she shared. "I don't even think he brought anything up of that nature until I was like 20!"
