[18][19] Mussolini was taken under the wing of her aunt Sophia Loren for a while and started a career as an actress in the Italian film industry during the 1970s.

She claimed that her relations with Gianfranco Fini, leader of the Alleanza Nazionale, never were very good; she then later withdrew, resigning over differences with him at least once.

[28][29] Mussolini suddenly left the National Alliance on 28 November 2003, following the visit of party leader and the Deputy Prime Minister Gianfranco Fini to Israel, where he described fascism as part "the absolute evil" with regard to the Holocaust as he apologised for Italy's role as an Axis Power during the Second World War.

[46] In November 2007, remarks by Mussolini triggered the collapse of the far-right Identity, Tradition, Sovereignty grouping within the European Parliament.

[49] In 2022, she supported the anti-homophobia "Zan bill" and she refused to provide her gender information on her MEP identity card after returning to the European Parliament.

[51] She has used Twitter to defend the memory of her grandfather from critics such as actor Jim Carrey, and fans of Scottish football club Celtic F.C.

[7] She took part, as contestant, in Milly Carlucci's Ballando con le stelle and in Carlo Conti's Tale e quale show obtaining success.

In November 2022, Mussolini returned to politics to replace Antonio Tajani as a Forza Italia MEP after his election to the Chamber of Deputies.
