The 'Born This Way' singer has purchased an apartment in the Fitzrovia area of the UK capital so she no longer has to stay in hotels when she comes to the city.
The property is located in a luxurious new development which is not yet complete.
The building will boast a modern concrete exterior, floor-to-ceiling windows, four luxury penthouses, a roof garden and a communal courtyard.
A source said: "She had been staying in The Lanesborough hotel every time she visited London but because she is over so much she has decided to go for it and invest."
The area of London has become a popular destination for celebrities in recent years.
Madonna previously owned a townhouse in the area, which she shared with her ex-husband Guy Rictchie, who has since bought two mansions in Fitzrovia in May 2010 which he is combining into one house.
Perhaps Gaga has bought the apartment to share with her boyfriend Taylor Kinney.
The pop superstar recently asked 'The Vampire Diaries' actor to move in with her and as well as snapping up the flat in London, the couple have been looking at properties in her native New York and his home state, Pennsylvania.
