But France's first lady has likened herself to the colourful singer in an interview with French magazine Obesession, while discussing how she manages the pressures of life in the public eye.
“With my experience with the media, I am Lady Gaga!” she said.
And like the Born This Way hit maker, Carla admitted that she often dons wigs – although her motivation is going incognito rather than thrilling audiences.
“Notoriety does not weight heavily on me, and then I disguise myself literally as well as figuratively,” she added.
