Kelsey Grammer has a possibly pregnant new girlfriend?

kelsey-grammer-wife-camille.jpg Kelsey Grammer -- in the midst of a divorce from his third wife -- has a new blonde British girlfriend.

They've already been photographed -- wearing matchy-matchy sportswear -- holding hands in New York, where he's living and starring in "La Cage aux Folles" on Broadway.

All we know is that her name is Kate and she may be pregnant. If it's true, this will be the second time the "Frasier" star has started a new family while married. His 18-year-old daughter was conceived with a hairdresser during his marriage to second spouse Leigh Anne-Cushany.

Oh, and he has three other kids, two (ages eight and five) with Camille Donatacci  and one ( "Greek" star Spencer Grammer, age 26) from his first marriage.
