Calling all party people. Summer may be over, but Beyoncé gives us another reason to celebrate with the vibrant video for her Kanye West-produced single “Party” off her fourth album 4. The pop megastar throws a backyard bash in a trailer park with some of her best friends. Solange plays DJ, Kelly Rowland reunites with her Destiny’s Child groupmate, and J. Cole makes his way over in a blue Bugatti. But it’s B who steals the show with her funky fashion and bubbly personality. This is one party you won’t want to miss.
