"I'm glad that I decided to do the show because it's been a diversion," the 42-year-old former Playboy model said in an interview with The Associated Press. "I have these wonderful, five very strong, successful women right there supporting me through this."
In the season premiere, which airs Thursday, Kelsey Grammer is seen leaving for New York to star in Broadway's "La Cage aux Folles." His ex-wife says at the time she had no idea divorce was on the horizon and was preparing to relocate her family to New York.

"It was hard for me. It definitely brought a tear to my eye," she said of seeing the first episode. "... I think I give him a kiss (goodbye) and I say 'I love him.' I was supposed to move in that summer."
Watching the episode was also an emotional experience for her fellow housewives.
"You were totally blindsided," said castmate Lisa Vanderpump. "It was hard to watch for us as well. It gives me goosebumps thinking about it."
Vanderpump, a British restaurant owner and mother of two, says Grammer's divorce brought the women closer together.
"It was tough for her, very tough. ... You're not just opening the gates to your house, you're opening the gates to your heart, your life," Vanderpump said. "And it's like an express train, sometimes things kind of run away with you."
"The Real Housewives of Beverly Hills" airs Thursdays at 10 p.m. ET.
Earlier this week, Kelsey Grammer and his new girlfriend, Kayte Walsh, revealed she had just two months after announcing they were expecting.
"We lost our unborn child about six weeks ago," they said in a statement obtained by People magazine. "We would like to thank all of those who expressed kindness and concern but we needed a little time to heal, time to find some solace before we publicly acknowledged our loss."
