The former 'Real Housewives of Beverly Hills' star is entitled to 50 per cent of the money from the former 'Frasier' actor's 401K account from the time of their marriage in 1997 until they went their separate ways in 2010.
According to court documents obtained by PEOPLE, a judge signed off on the order last month.
Camille - who has children Mason Olivia, 16, and son Jude Gordon, 13, with Kelsey - filed for divorce from the 62-year-old star in July 2010 and their separation was officially completed in February 2011.
Kelsey - who has five kids from other relationships - went on to marry Kayte Walsh a few weeks later.
The 49-year-old beauty has also found love again with lawyer David C. Meyer, who she got engaged to last week.
She wrote on Twitter: ''Party night with my love. We have a secret.. guess (sic)''
The star - who has been dating David for more than a year - then retweeted a story about the pair getting engaged and thanked fans for their well wishes, confirming the news.
A source close to the couple told the publication: ''They're just in love.
''There's a casualness and easiness to their relationship. They're a really happy, kind couple. He really loves her for her.''
In March, Camille admitted she was considering returning to 'The Real Housewives of Beverly Hills'.
She said: ''It's something I've been toying with the last three years. I've been asked. Maybe next year, we'll see. You know, after the reunion and after this season, and after casting, we'll see how they feel about it. We'll be back and we can all discuss it.''
