The 45-year-old singer, whose last album dropped in 2008, took a break from music to serve as first lady. Her latest effort, "Little French Songs," out Monday, pokes fun at an affected "penguin" widely believed to represent her husband's successor President Francois Hollande.
According to The Hollywood Reporter, Bruni felt slighted when Hollande didn't escort her and her husband out of the Elysee Palace as he took office last year.
"He takes on the air of a sovereign, but I know the penguin doesn't have the manners of a lord," she sings in French on the new track, "The Penguin," a term used in France to describe someone self-important without grace.
“Hey penguin, you look all alone in your garden. If one day you cross my path, I’ll teach you to kiss my hand," she also sings.
Bruni has not said whether Hollande inspired the song.
"It's a song about the ill-mannered, disagreeable people, who remain a mystery to me" she told Le Nouvel Observateur. "Some think that I'm talking about journalists: that's false."
Bruni's first single, "At Keith and Anita's Place," refers to a day with former flame, Mick Jagger, and his Rolling Stones bandmate Keith Richards.
