Ramona Singer might be a very tough woman on the outside, but according to sources close to the blonde beauty, she's having a hard time putting herself together behind closed doors. According to a new report, Singer reportedly feels "humiliated" by her husband Mario Singer and him stepping out with his mistress Kasey Dexter so publicly following their separation news.

Why Did Ramona Singer Send Kasey Dexter A Threatening Letter?

After Ramona made the announcement that she is divorcing her husband after over 20 years of marriage, Mario was spotted several times with Dexter while the two were out and about in New York City.

A source close to the star tells RadarOnline on Wednesday, "Kasey has now dyed her blond hair black, and Mario was all over her at the Women's Health Party Under the Stars in Bridgehampton on Saturday night. Mario was openly grabbing her butt, and the two were making out in front of everyone. It was very awkward."

Apparently, the soon-to-be ex-couple was also having financial difficulties before their split as well.

The source added, "Ramona is humiliated and embarrassed because she has rented a house in the Hamptons for the month of August. Ramona and Mario chose to rent out their family mansion in the Hamptons for financial reasons."

Meanwhile, Ramona's sister Sonya Mazur recently opened up about her heartache and how she thought Ramona and Mario had the "perfect marriage."

Mazur told RadarOnline last week, "I never thought Mario would do something like this to my sister. I can't believe this happened, period."

She added, "I'm shocked to hear she's going to leave. I think it's unbelievable. I thought they were the perfect couple."
