Frankel spent the day of New Year's Eve on the beach in Miami with new beau Michael Cerussi. Bethenny's daughter with estranged hubby Jason Hoppy is reportedly with the couple on the trip.
As if all this wasn't enough to irk Hoppy -- whose divorce from Bethenny is still not quite final -- Frankel tweeted, "NYE day & i'm exactly where i want to be with exactly who I want to be with."
Ouch.
