The 'Poker Face' hitmaker - who reaches the milestone age today (28.03.16) - sang for her guests, which included fellow pop stars Taylor Swift, Lorde, Kylie Minogue and Lana Del Rey, crooner John Legend and his model wife Chrissy Teigen, producer Mark Ronson, 'The Voice' coach Pharrell Williams, and Ashlee Simpson and her husband Evan Ross, 'Real Housewives' star Lisa Vanderpump and actress Kathy Bates, at the bash at No Name Club in Hollywood.
A source said: "She sounded amazing."
The group also ensured they serenaded the 'Bad Romance' singer.
The insider added to E! News: "Everyone sang 'Happy Birthday' to Gaga and it was a perfect night."
The lucky birthday girl was also given a number of gifts, with TMZ reporting she received a famous sketch by the late Michael Jackson - who died in 2009 - called 'Dancing Feet'.
Another of the drawings sold in 2010 for almost $25,000, proving Gaga has some generous pals.
And it may be that the star had something else to celebrate as when she arrived with fiance Taylor Kinney - who she got engaged to in February 2015 - she was wearing a gold band on her ring finger, instead of her diamond engagement ring, fuelling speculation the couple have secretly tied the knot.
