Kelsey Grammer's gonna be a grandpa!

February was a busy month indeed for the Frasier star's family.

A source close to the 56-year-old actor, who wed new love Kayte Walsh Feb. 25, tells Us Weekly that his actress daughter Spencer is expecting!

The Greek star, 27, wed James Hesketh on Feb. 11 at City Hall while her famous dad and stepmom Walsh, 29, looked on.

The insider adds that the pregnancy is "early on."

How early? The source reveals that Spencer found out she was pregnant right before her wedding!

So far, the TV star (her mom is Grammer's first wife Doreen Alderman, whom he divorced in 1990) has been mum on her baby-to-be.

But her little one will have potential playmates in a very young aunt and uncle: Mason, 9, and Jude, 6, Kelsey's daughter and son with third wife, Real Housewives of Beverly Hills' Camille Grammer (they divorced in early February).
