?Lady Gaga [1] and Bradley Cooper [2] spent part of their Labor Day weekend together in LA. The duo was spotted on a shopping trip together in Malibu on Sunday, where they exchanged smiles and waved at passersby. We last saw the two out together for a splendid motorcycle dinner date [3] this past April. The pairing isn't all that random, we're aware. After all, Bradley and Lady Gaga have partnered up for the upcoming remake of A Star Is Born [4]. Even so, we can't help but be enthralled by the friendship that seems to have bloomed outside of their professional endeavors.
