Seven is the lucky number for Kelsey Grammer!

A rep for the former Frasier star, 61, confirms to PEOPLE that he and his wife Kayte welcomed their third child together and Grammer’s seventh total. Auden James Ellis Grammer was born on Monday, Nov. 14, weighing 7 lbs. and measuring 21 inches long.

“Both mother and son are doing great,” a rep for the couple tells PEOPLE.

Auden’s name has quite the story to go along with it.

“The name was chosen to honor the great poet W.H. Auden, and James is after another great poet and singer James Taylor — two of our favorites,” the couple say in a statement.

“Ellis” is all in the family, though: It was Grammer’s maternal great-grandfather’s name.

“He was a colorful character, to say the least, and we wanted to give the name a second chance,” add the Grammers, who were married in 2011.

Auden joins siblings Kelsey Gabriel Elias, 2, and Faith Evangeline Elisa, 4, plus Grammer’s children from previous relationships: daughters Spencer, 33, Greer, 24, and Mason Olivia, 15, as well as son Jude Gordon, 12.

In fact, one of Grammer’s daughters — Greer — is the one who spilled the beans about her new sibling’s upcoming arrival in September.

“My dad loves babies,” she told PEOPLE in 2014 shortly before Gabriel was born. “He loves having children and he’s always wanted a really big family, so he’s just really excited to have a new little life in the family.”

“It gets hard for other people [to keep track of his children],” she added at the time. “People get confused with how the relations work. There’s going to be so many of us. It’s funny.”
