In a recent interview, Billie Eilish was asked who the last famous person she texted with was. You can check out her response and Shawn Mendes' subsequent response below. Is this a big deal? Meh. He's an early 20-something and she's 16 or however old she is, so I'm guessing he was reaching out professionally. Or possibly not based on her reaction to the story telling. Either way it's all socially... awkward. So very on brand across the board.
