Michael Buckner/Variety/Getty Will Ferrell Dressed as a Medieval Lord to Embarrass His Son Magnus at Prom — See the Hilarious Photo! In June, Ferrell's son Magnus shared a hilarious video to his TikTok account, posting two different images side-by-side. The first showed a selfie of Magnus in what appeared to be a recording studio, with the words "rating things my dad has done" across the photo. The second picture showed Ferrell dressed as a medieval lord, posing next to Magnus, who wore a checkered suit and black-and-white polka dot shirt. "Dressed as a medieval lord to embarrass me at prom 10000/10," Magnus wrote across the picture. "True story," Magnus captioned the video. Last October, the actor DJed at a Sigma Alpha Mu fraternity tailgate party at the University of Southern California ahead of the football game against the University of Arizona Wildcats during Trojan Family Weekend. In a TikTok video, the USC alum could be seen clapping alongside students to Survivor's “Eye of the Tiger” as he helmed the DJ booth. Ferrell was outfitted for the occasion, with his headphones worn on top of his backward USC red cap. The Barbie actor has been an active USC alum since he graduated from the school in 1990. He delivered the commencement speech to the graduating class of 2017 and contributed to funding the first-ever full scholarship for the women’s soccer team with his wife in 2018. Trojan blood even runs in the family, as Magnus is currently enrolled at USC, according to his LinkedIn page. Close
