Actor Kelsey Grammer is set to become a dad again - his wife is pregnant.

The former Frasier star and his wife Kayte, who wed in 2011, are already parents to 19 month old Faith Evangeline Elisa and, according to U.S. reports, they will be welcoming another baby later this year (14).

In 2012, the couple announced it was having twins, but the Grammers lost their son in utero.

The actor has four other children from previous relationships - Spencer, 30; Greer, 22; Mason, 12, and Jude, nine.

Greek star Spencer also made Grammer a first-time grandfather in 2011.
