They've got the beat! Though the Flying Burrito Brothers' first and most popular album was released in 1969, the country rock band's influence is alive and well. Whether they themselves are fans (or more likely, their parents), both Shiloh Jolie-Pitt and Cruz Beckham have been spotted wearing the band's signature tee, originally worn by bandleader Gram Parsons. Four-year-old Shiloh wore the Worn Free Flying Burrito Brothers T-Shirt ($45) around her family's Budapest rental this week, while now 5-year-old Cruz was caught in the shirt early last year.
