The 'Cake' singer celebrated the Thanksgiving holiday on Thursday (November 22) with her family in Peru, where she continues her 'Born This Way Ball' tour.
She relayed the events of the late evening break-in via her official Twitter account where she wrote: "Monster fact when Gaga is asleep try to break into the garage, sing loud as possible, + ring the doorbell repeatedly… happening now… bad kids.
"Thanksgiving story: woke up for leftovers in kitchen (naked) - stumbled on security camera revealing 35 monsters in my garage… why… I love u."
Despite the inconvenience GaGa joked about the incident, adding: "I should be mad I guess except I tried to figure out how to slide stuffing under the door, but theres no cat-flap."
GaGa is gearing up for the release of the music video for her new single 'Cake', directed by photographer Terry Richardson.
