"Would I have done the show knowing I was going to be going through a divorce? No. I don't think anybody would make that decision," Grammer, 42, who split this summer with her husband of 13 years, Kelsey Grammer, tells PEOPLE.
But there turned out to be a silver lining: the support of her costars. "I'm having a great time," she says. "I have to say it's been a fantastic diversion considering what I'm going through in my personal life."
Those costars – Taylor Armstrong, Lisa VanderPump, Kyle Richards, Kim Richards and Adrienne Maloof – have become fast friends. "These girls have been amazing, very strong and smart and successful in their own way, and they have been there with me through this whole [separation with Kelsey]," Grammer told PEOPLE on Monday at an interior-design event in Los Angeles.
Camille filed for divorce from Kelsey in July. They have two children – Mason, who turns 9 this month, and Jude, 6. "I'm hoping we can co-parent in a civil manner," Camille says. "That's what my hope is."
For now, she has her show to focus on – and it's one worth watching, Grammer says.
"I think it's a notch above the rest [of the Real Housewives shows]," she says. "Even though I like the other shows, I'm just going to say: This is Beverly Hills. It's opulent, it's glamour, it's centered around celebrity and Hollywood. It's the real deal."
