Kelsey Grammer’s brood is getting bigger.

The 70-year-old actor’s wife, Kayte Walsh, is pregnant with their fourth baby together, Grammer’s eighth.

Daily Mail was informed by a source on Tuesday that Kelsey is excited to have the opportunity to fully embrace fatherhood once again. The source added that he has provided great support to Kayte during her surprising pregnancy, leading to a renewed sense of passion in their relationship.

The source continued, “After giving Frasier one last go, he has hung his hat up on that character and is ready for the next phase of his life. He is looking forward to embracing the hands-on parenting he missed in the past.”

Photos obtained by the outlet showed Walsh, 46, and Grammer out for a stroll in London Tuesday looking happier than ever.

In the photos, Walsh is wearing a flowing navy blue nap dress, which appears to show her growing baby bump.

The pair were joined by their three children Faith, 12, Gabriel, 10, and son James, 8.

A rep for the actor did not immediately return Page Six’s request for comment.

The former flight attendant and Grammer got married in February 2011 in New York City two years after they met on a plane in 2009.

At the time, the “Frasier” alum was married to Camille Grammer, with whom he shares daughter Mason, 23, and son Jude, 20.

The former couple tied the knot in 1997 and called it quits in 2010.

Their divorce was finalized the following year, with Camille, 56, awarded a $30 million settlement.

Kelsey, who has admitted to cheating on the “Real Housewives of Beverly Hills” alum, has been married two other times.

The “Cheers” alum first wed Doreen Alderman in 1982, and the exes welcomed daughter Spencer, now 41, before calling it quits in 1990.

Kelsey and Leigh-Anne Csuhany were husband and wife from 1992 to 1993.

Between his first two marriages, the Golden Globe winner became the father of daughter Greer, now 33, with his then-girlfriend Barrie Buckner.

Kelsey told The Guardian in 2018 that he “regretted … earlier in [his] life” being so “busy” with work that his family life “suffered.”

The Emmy winner noted, “Honestly, the beauty of being an older dad is you get a chance to kinda try it again. That’s been a real gift.”

Four years later, he elaborated on his “failings” as a working father to his eldest child, specifically.

Kelsey revealed in a 2022 People interview that he and Spencer had “made amends” and were in a good place of their “hot and cold” relationship.
