The Applause singer and her 33-year-old beau met on the set of her You and I music video in 2011 and started dating a few months later.

They split briefly in May 2012 however they were back together the following month and have been inseparable ever since, even holding a commitment ceremony in October last year.

Gaga recently spoke to Howard Stern about her relationship, admitting that she would marry the Chicago Fire star if he asked her.

"He is the right guy," she gushed, "How do we know? It's this feeling..."
