Lady Gaga was serenaded by 20,000-plus fans for her 25th birthday following her concert at Los Angeles' Staples Center on Monday, and RadarOnline.com has the pictures and video for you.
The Just Dance singer was presented with the cake by three beefy backup dancers, and was no slouch in the sexy department herself, with her flat tummy. Then, the entire crowd sang "Happy Birthday" to the pop superstar. (Seriously, does life get any better?)
Gaga wished for happiness for all her "fans around the world" before blowing out the candles.
Earlier Monday, the New York native also got a birthday call from talk show host Ellen DeGeneres, who sang Happy Birthday to her on her show.
“Gaga you were born today, Gaga you were born today, Gaga you were born today!” Ellen sang to the superstar diva, to the tune of her hit Born This Way (which sits atop the Billboard charts for the sixth straight week).
Gaga’s next album, also titled Born This Way, hits stores May 23.
