Bringing your newborn to a party at the Playboy Mansion is one thing, but ordering your children not to mention their mother's name while under your roof is another level of self-indulgence altogether.

Camille Grammer, one of the stars of Real Housewives of Beverly Hills, has two kids with the Boss actor, and says the former couple are "spending a fortune" communicating through lawyers because he "refuses" to speak to her, despite her attempts to be "amicable."

She said: "[It's] kind of sad I found this out, that they are not allowed to same my name in the house. So these poor kids, my daughter and my son, can't say my name in their father's house. He doesn't speak to me at all. So it's very, very difficult because I've reached out to him. I think it's very important to be amicable to raise children and he refuses to. There's just so much I can do at this point."

Despite her grievances, Camille, 44, admits she "misses" Kelsey - who is now happily married to his fourth wife Kayte Walsh, with whom he has the aforementioned newborn, a 5-month-old daughter Faith - and would love to be back on speaking terms with the 57-year-old star.

Speaking in an interview on Anderson Live, she added: 'I mean, we were best friends and I miss my best friend. So, it would be nice. I know it's never going to be that relationship or that friendship for whatever reason, but just for us to get along, for the sake of our children."
