Demi Lovato isn't afraid to show off her goofy side every now and then, but on Sunday (Sept. 6), the 23-year-old singer took her playfulness to a whole new level.

The 23-year-old singer has been in Paris, France promoting her new single "Cool For the Summer" and shared with fans on Sunday that she took some time to visit the world famous Louvre Museum, home of the Leonardo Da Vinci's famous painting, the Mona Lisa.

"Today in Paris I saw the #MonaLisa again but this time I had a theme song... #ihadto," Lovato wrote in the caption to her first video. That theme song? Big Sean's "Mona Lisa."

In her second video, Lovato is seen smiling and dancing to the song while the Mona Lisa hangs on the wall behind her while a group of museum attendees look at her with a confused look.

We're not sure if Lovato actually played the music out loud for the video, as that would most definitely be a museum faux pas, especially in one of the world's most famous historic buildings. But we can't help but think that a part of that smile on Mona Lisa's face is reserved for Demi's antics.
