The 24-year-old singer began dating the 29-year old barman for a second time last year, having previously had a relationship with him four years earlier before she found fame after meeting the failed rock drummer in a New York bar.
The loved-up pair dated for a couple of years before splitting up just before Gaga went global with her first album in 2008. But after getting back together, the loved-up pair is taking things more seriously this time around, according to the Daily Star.
"She and Luc are in no rush to name a wedding date. She doesn't even have a proper ring because he couldn't afford one," the Daily Telegraph quoted a source close to Gaga as reportedly saying.
