According to NME, the former US president spoke openly about his love of singing along to his favourite tunes while scrubbing up, and it comes as no surprise that he is quite the Bruce Springsteen fan.
The revelation was made on Barack's Spotify podcasts which he hosts alongside the Born in the USA singer - a long-time friend of his.
Bruce and Barack launched their podcast, Renegades, on 23 February on the music streaming app.
"I sing in the shower. I sing outside of the shower. I am unembarrassed about singing... My daughters and my wife sometimes roll their eyes," Barack was quoted as saying.
The 44-track playlist, shared by Spotify on Wednesday, also includes songs by The Beatles, Marvin Gaye, Jill Scott and Beyoncé.
