Gaga, whose real name is Stefani Germanotta, announced the couple's engagement on Instagram with an intimate snap of the ring and the caption:
'He gave me his heart on Valentine's Day, and I said YES!'
The pair has been dating since 2011, when they collaborated on the music video for her song 'You And I', and she has since said in interviews that she knew he was 'the one'.
