Although they have been seeing each other for months, the pair kept quiet about their association until Louise's colleagues at Today FM, Ian Dempsey and Ray D'Arcy, outed the couple.
"He's romancing me," radio host Louise admitted yesterday, before adding that it was only "early days" yet. "So far, so good -- we'll see how it goes."
The striking 27-year-old brunette said that she appreciated his taste in clothing.
"He does his own thing, he doesn't wear what people think he should -- that's refreshing in itself."
Louise, who was speaking from Dundrum Town Centre yesterday, where she highlighted the shopping centre's extended Christmas hours, said that she could not believe her colleagues had made her relationship with Galvin (32) public last week when they forced an admission from him.
"I was a little surprised," she admitted.
"There is great craic in there and if they weren't pulling the mick, I'd be shocked, so it's fine."
