“I was at my parents’ house for Christmas and I got a DM from a fan —if you’re watching you know who you are. They were like, ‘Just so you know, Sam Bird has followed you and liked a bunch of your pictures and then unfollowed you within the last couple of months,'” the Lindsay Lohan’s Beach Club alum explained in a YouTube video posted on Bird’s account. “So, he happened to be at a soccer game that day and I just replied the first Story that I saw. … So I DM’d him and literally, that same night, he was like, ‘I’m going to book a trip to see you.'”
