The actor, 55, and his new girlfriend, Kayte Walsh, 29, are expecting a baby together, her father told the Daily Mail and Grammer's rep confirmed Thursday.
"It's great news and we are very pleased for them both," Walsh's father, Alan, told the U.K. paper, adding that he has not met the actor yet and found out about the pregnancy "a couple days ago."
"Kayte and Kelsey are happy to confirm what Kayte's father told the London Daily Mail is true," says Grammer’s publicist, Stan Rosenfield.
The news comes one month after Grammer's wife of 13 years, Camille Donatacci, filed for divorce.
The Cheers and Frasier star has two kids with Donatacci, daughter Mason, 8, and Jude, 5, and two older daughters, Spencer, and Greer, from previous relationships.
