Lady Gaga achieves Facebook milestone
The singer now has ten million fans on the social networking site, according to Famecount.
This puts her ahead of US president Barack Obama and other major music acts such as Britney Spears and Taylor Swift.
It also means that Lady Gaga is the first living person in history to have more than ten million Facebook fans.
Daniel Dearlove, spokesman for Famecount, commented: "Achieving ten million fans is a remarkable testament both to her stardom and to Facebook's extraordinary reach."
Speaking to BBC Radio 1's Newsbeat, he added that Lady Gaga's fanbase on Facebook has more than doubled this year, which makes her the fastest-growing star at the moment.
The news comes ahead of a series of UK dates for Lady Gaga later this year, which includes three gigs at the Odyssey in Belfast.
She is also set to perform at the O2 Arena in London in December.
