Kelsey Grammer is going to be on daddy duty for the fifth  time -- with two more babies on the way!

The Boss actor's wife Kayte Walsh is pregnant with twins, his rep confirms to Us Weekly. UPDATE: After winning a Golden Globe for Best Actor in a TV series, Grammer, 56, gabbed with reporters about the big news. "I am really looking forward to meeting these arrivals!" Grammer exclaimed. 

Walsh, 30, will be "extraordinary" as a mother,  Grammer gushed. "She is one of the most loving, warm human beings."

The twins will be the couple's first children together; Grammer, 56, wed Walsh, 30, at a lavish February 2011 wedding in NYC, just weeks after the finalization of his divorce from third wife, Real Housewives of Beverly Hills star Camille Grammer.

The Frasier star (who is up for a Golden Globe this Sunday for his TV performance in Boss) has two children with Camille (Mason, 10, and Jude, 7), an older daughter, actress Spencer Grammer, 28, with his first wife Doreen, and another daughter, Kandace, with ex-girlfriend Barrie Buckner.

Kelsey and Camille's 14-year marriage famously disintegrated on the first season of Real Housewives of Beverly Hills; he met flight attendant Kayte while staying in NYC for a gig on Broadway's La Cage Aux Folles.
