Speaking to Fox News last year, Katharine told the station how she and her boyfriend – who is 35 years her senior – have a connection.
“I have a glass of wine — he doesn’t drink — and we just talk.” It’s our time together that we always pay attention to,” she revealed.
She added, “There’s always something to talk about, whether it’s our family, our son – it’s our time, we just want to get back together.”
The LA native noted that they “love going to the movies or having dinner together,” admitting, “There’s nothing extravagant about what we love to do.”
The couple, who first met on American Idol in 2006, released a Christmas EP titled Christmas Songs last holiday season.
