Yes, Ramona Singer Is Still Hanging out with Tom D'Agostino's Ex Missy — and We Have a Clue about How Luann de Lesseps Feels about It

Luann de Lesseps and Tom D'Agostino finalized their divorce in 2017 — but reminders of him live on in The Real Housewives of New York City universe.

On August 5, Ramona Singer posted a photo with one of Tom's exes, Missy, who appeared on the show. "Fun weekend with my girl [Missy Pool]!" Ramona wrote.

This isn't the first time Ramona and Missy have hung out — she also invited her to her housewarming party in Season 9. And you may recall that Missy and Tom used to date before he and Luann became exclusive. Tom also had that infamous hot mic moment with Missy; check that clip out above.

And as for how Luann feels about this friendship? We have a feeling the cabaret star is unbothered; she actually "liked" the Instagram post!
