"I don't want to be involved with the wedding, not at all," the Real Housewives star says of Kelsey Grammer's upcoming nuptials to Kayte Walsh. "But I don't begrudge him his happiness."
In fact, Camille has another obligation for the same night her former husband plans to tie the knot in New York City.
"My daughter has a talent show that day that she's been working on for two months now," Camille said in an interview with PEOPLE. "I told her, 'Mason, you can go. Please, if you want to go to your Daddy's wedding, please do,' and she said, 'No, Mommy. I want to go to my talent show.' "
Although her son Jude, 6, will be at the wedding, Camille says, "I'll be the proud mom in the front row" of the talent show, where her daughter Mason, 9, will dance to the song "Fame."
"If Mason wanted to go, I'd let her go," Grammer says. "I would never hold my children back from that. I would never want them to resent me for holding them back from their father's wedding."
Will Camille send Kelsey and Kayte a wedding present? "I said jokingly to somebody, 'I'll send a pair of sharp steak knives and a crock pot,' " she says with a laugh. "But, no, I have no interest in sending him a wedding present."
Grammer, it seems, has other things to worry about, including recently taping a guest spot on the sitcom $#*! My Dad Says.
"I was so excited to be a part of it," she says of the finale episode, which airs Thursday (8:30 p.m. ET) on CBS. "I was terrified going on the set ... I felt intimidated but I did my table read and ... I got some laughs, so that's a good thing."
Grammer, who "basically did a spoof on myself" for the episode, still hasn't decided whether she'd do another season of that other show she's been on, The Real Housewives of Beverly Hills.
"I'm completely on the fence and I've spoken to producers and that's something that we need to decide together," she says. "There's a part of me that really wants to do it and there's another part that's nervous because of what I've experienced with it."
