Some of the biggest names in show business came out for Sin City's first grand prix in 40 years.
The Formula One Las Vegas Grand Prix saw the iconic Vegas Strip transform into a star-studded circus of race fans and celebs alike, who came out on Saturday for the first F1 race held in Sin City in over 40 years.
After months of preparation, construction, riled-up locals and fanfare, F1's big day came over the weekend, and dozens of movie stars, models and musicians showed up to check out the high-octane action.
Pitt rocked layers of beige and tan, paired with yellow aviators and blue jeans, as he walked into the paddock during Saturday's race.
People's Sexiest Man Alive 2023 himself, Patrick Dempsey, was also on hand for the big race. The 57-year-old actor will soon be seen racing cars on the big screen in the upcoming biopic Ferrari. Dempsey stars as famed Italian racing icon Piero Taruffi.
