In court papers, Bushnell, 53, claims Askegard had an affair, according to the New York Post, with ballerina Georgina Pazcoguin. The two have worked with the New York City Ballet for the past eight years.
In a statement about the divorce, Bushnell said of Askegard, "We had some wonderful times in our nine-year marriage, and I still care about Charles as a person. I respect his desire to pursue his own happiness and hope that we will continue to be friends in the future."
But Bushnell may not have known about the affair at the time of the initial divorce filing.
"The divorce was proceeding amicably, then Candace found out about Georgina and became very upset," sources tell the Post. "She believes their affair could have gone on for some time. Humiliated, it was her idea to take the unusual step of naming Georgina as a co-respondent in the divorce papers."
Askegard left the New York City Ballet in October to form his own company. He and Pazcoguin performed together at the 2011 Alzheimer's Association Rita Hayworth Gala later that month.
Bushnell and Aksegard were married in 2002.
