You'll recall ... Luann and Rich first started dating back in 2018, when he was in the middle of divorcing his wife. The pair dated for a short while, until Rich dumped her right before her stint in rehab.
Luann tells us she still has a strong connection with Rich ... and not only because he's helping her become a rising cabaret star. Although, it's clear she's really happy with her nationwide tour, so far.
As for what many call a major no-no -- mixing business with pleasure -- Luann's enjoying it. One woman's taboo is another's treasure.
