Grzegorz Matlok, 29, was wrestled to the ground by bodyguards at 5.30am inside the heavily-fortified ten-bed Georgian townhouse.
He is said to have climbed in after smashing a side window while the singer was in the US following the death of her grandmother.
The security team told police who arrested Polish-born Matlok that he had stalked her before.
The huge home in Marylebone has an array of CCTV cameras and a state-of-the-art alarm.
But a senior police source told The Sun: "Something dreadful has happened here. The security around the world's most famous pop star should be impregnable."
Matlok, of no fixed address, was seized on Saturday.
