Bethenny Frankel is dating a married man -- and she's not afraid to say it.

After rumors began swirling regarding her latest romance, the Real Housewives of New York City star took to Twitter, where she confirmed her new boyfriend, New York banker Dennis Shields, is legally married.

Frankel's tweet came in response to a fan who revealed Frankel's co-star, LuAnn de Lesseps, had spoken of the romance during an interview last week.

"She calls me a hypocrite, but really she's the hypocrite. I'm the one getting married, I'm engaged, and Bethenny's still trying to get a divorce. You know, it was in the Daily Mail...she's dating married men, not me," de Lesseps revealed to E! News.

De Lesseps also Frankel dissed Frankel for her frequent and angry outbursts.

"I think that Bethenny loves drama and I think that she's happiest when she's bickering," she explained. "I think there's a lot of anger there. I think that, you know, she's still trying to get divorced and that might have something to do with it. It seems like she's really tightly wound and, you know, looks like she needs a vacation."

Frankel initially denied her relationship with Shields earlier this year, but last week, the romance was confirmed.

"They've been dating since at least the holidays," a source told E! News, adding that the couple recently enjoyed a vacation with her co-star, Carole Radziwill, and her boyfriend, Adam Kenworthy.

And while Shields has not yet filmed scenes for The Real Housewives of New York City, he did show up during production one day but steered clear of the cameras.

In February, after rumors of her romance with Shield hit the web, Frankel seemingly denied the reports, telling fans she's constantly accused of having new men in her life.

"FYI, I'm dating abt 65 guys," she wrote on Twitter. "They're all married, rich, famous & I'm pregnant w multiple babies. Oh & Guess what? I'm married too."
