Born 7 March, 2004, Magnus is taking after his dad and seems to love the spotlight. Magnus is a musician and has released four singles so far, and in December 2022, per People, Magnus and his band opened for the Psychedelic Furs at a benefit concert in San Diego. Of course, Magnus's dad hopped onstage to accompany him, playing his signature cowbell in a reference to his infamous "Saturday Night Live" gag.
