The 38-year-old Bad Romance singer has been in a relationship with entrepreneur Michael Polansky since 2019 and they became engaged in April this year.
As Polansky has a reported net worth of $600 million (£470 million), he is able to go all out to impress the singer - and did just that one Valentine's Day.
Opening up to Rolling Stone magazine, Gaga recalled, "For Valentine's Day, he said, 'I have a surprise for you.' He turned his office into a music studio. I mean, it's kind of romantic!"
The multi-award-winning singer has also revealed how her future husband effortlessly builds her confidence every morning.
She said, "Something that Michael said to me every day that I was working is, 'Go do what you were born to do. And do it with every cell in your body, and have fun and be confident in your music.'"
Polansky has dipped his toes into the music world himself and even has a writing credit on Gaga's latest single, Disease.
The track, which was released in October, is the lead single from the star's forthcoming seventh studio album - but it stalled in the charts, reaching only number 7 in the UK, and 27 in the USA.
