Kelsey Grammer: A Daddy Times Five!

Not quite an Octodad, but give him time: Kelsey Grammer has a fifth child on the way.

The Boss star — who is nominated for a gong at tonight’s Golden Globe Awards — and his wife Kayte Walsh Grammer, 32, are expecting a new addition later this year.

The tot will be Kayte’s first and Kelsey’s fifth. Walsh and Grammer — who married in February 2011 — suffered a miscarriage in 2010. Kelsey and Kayte announced the pregnancy the previous August, just weeks after the star confirmed his pending divorce from Wife No. 3, Camille.

The 56-year-old showbiz veteran is already dad to son Jude, 7, and daughter Mason, 10, with Real Housewives of Beverly Hills star Camille Grammer. He is also dad to Greer, 19, with ex Barrie Buckner and Spencer, 28, with Doreen Alderman.

Kelsey recently became a grandpa after Spencer gave birth to son Emmett, who is 3 months old.

Kelsey remains in the throes of a acrimonious custody battle with Camille, 42. The former Frasier actor is suing his Playboy model ex for sole physical custody of their two young children; a daughter Mason, 9, and a six-year-old son, Jude.
