Mark-Francis Vandelli

Mark-Francis Vandelli (born 14 October 1989) is an English television personality. He is best known for his role on the E4 series Made in Chelsea.

Mark-Francis was born on 14 October 1989 in London, England. He is the only child of Marzio Vandelli, an Italian businessman who formerly owned a tile factory, and Diane Casserley. Vandelli was educated at Hill House School and St Paul's School, and studied Art History at University College London. While promotional material associated with Vandelli often claims that his mother is a descendant of a non-existent aristocratic Russian family named "Orlov-Romanovsky", she is largely of English descent with some distant Irish ancestry and one Russian great-great-grandmother who emigrated to England in the nineteenth century as an impoverished orphan.

In April 2011, Vandelli joined reality television programme Made in Chelsea as one of the original cast members.

In January 2016, Vandelli joined the third series of The Jump. He withdrew from the show on 9 February due to injury. In 2017, he starred in a Made in Chelsea spin-off entitled Mark-Francis' Big Night Out.

In 2023, Vandelli joined series 12 of Celebs Go Dating on E4.
