(Cover) - EN Showbiz - Kelsey Grammer tries to remain "very Zen" when his ex-wife Camille Grammer talks about him on The Real Housewives of Beverly Hills.

Kelsey and Camille finalised their divorce in February this year.

The actor doesn't want to respond to any of the comments Camille makes about him on the reality TV show.

"I'm not interested in replying [to Camille], I'll let them play their game," he said in a telephone interview with Australian radio programme The Kyle and Jackie O Show. "That's not my world and I let that play out. I try to get very Zen about it."

Kelsey and Camille have visited family court this year battling for parental rights over their two children, six-year-old son Jude and nine-year-old daughter Mason.

The actor hinted that there may still be some bitterness between them.

"From Aikido the basic premise is that the attacker must fall," he said mysteriously.

Kelsey has been married four times. He and his current wife Kayte Walsh wed in February of this year, shortly after his separation from Camille was finalised.

With domestic disputes, a marriage and a divorce, Kelsey acknowledges that this year has been quite intense.

"It's been a big year for me in so many ways, lots of changes. But I'm doing great," Kelsey said earlier this year. "This year's journey is about enhancing my life and Kayte is responsible for a great deal of that." (C) Cover Media
