The clash was captured by photographers. In photos, McGregor is seen lunging at the singer, with a crowd quickly separating them. It is not clear what started the altercation. Showdowns aside, much of the drama on the night revolved around the fashion. Country singer Kacey Musgraves wore purple, feathered Valentino Couture for the event, while Kardashian opted for a leather, mini Olivier Theyskens design and Fox wore a sheer Mugler gown. In keeping with more traditional red-carpet style was Cabello, who wore pink and red Alexis Mabille, and boyfriend Mendes, in a white Mans suit. A number of stars opted for vintage pieces, including <i>Deja Vu </i>singer Rodrigo, who wore a corseted pink 2001 Versace gown, and Madison Beer, who wore a Dolce & Gabbana dress that was also donned by <a href="https://www.thenationalnews.com/arts-culture/music/2021/09/04/40-facts-about-beyonce-as-the-star-turns-40/" target="_blank">Beyonce</a> at the 2003 VMAs.
