The couple has been officially dating since at least September, when Duff, 28, confirmed the relationship on “Good Day New York”.

“We have [found a little ‘like’ with each other],” she said at the time. “We’ve known each other for a really long time, and he’s a great guy and we have a lot of fun together. It’s nice to have that excitement in my life.”
