Why Is Sonja Morgan Still Upset with Luann de Lesseps' Fiance?

The saga surrounding Thomas D'Agostino and his past with Sonja Morgan and Ramona Singer is not over yet. And, as seen on Sunday's Watch What Happens Live, Sonja isn't quite ready to let Tom off the hook for the relationship they once shared before Luann des Lesseps. As she tells Bethenny Frankel in a preview for Wednesday's episode of The Real Housewives of New York City, she confessed to being with Tom just weeks before he hooked up with Luann. And while Luann and Tom shared their engagement news back in February, Sonja isn't about to forgive and forget. 

"Well that was back then. I mean, I don't know where we should start. We filmed that back then. Well, I'm still mad at Tom. I mean, he's my friend; I'm entitled to be able to be mad at him," Sonja told Andy Cohen on WWHL. "We know each other for 10 years. We're good friends, so he's not fessing up to the full truth."

Tom has tried to downplay his past relationships with both Sonja and Ramona, but things definitely got awkward when he ran into Sonja at his engagement party earlier this season. Sonja noted on WWHL that she sensed that Tom was feeling "uncomfortable" when they crossed paths because he's not really owning up their past.

Is This Awkward for Sonja?

The Tom-related drama will continued when RHONY airs Wednesday at 9/8c. Check out a preview below.
