Apparently, Langford, who celebrated her 21st birthday over the weekend, is a massive Lady Gaga fan — so much so that when DeGeneres asked her and costar Dylan Minnette about the moment they realized the show was reaching a certain level of popularity, Langford cited to the pop icon referring to her on social media.
“There was definitely a really big moment for me like a week ago,” Langford began. “I don’t have Twitter, but Lady Gaga tweeted at me, like reposted an interview where I was fangirling and wrote, ‘Katherine’ with a love heart. And I kind of freaked out a little bit.”
Langford freaked out a little bit more a few moments later when DeGeneres gifted her with backstage VIP passes to Lady Gaga’s concert. “Because you love Lady Gaga, I called her and she gave you — you’re going to go see her and go backstage and meet her,” the host announced.
Langford and Minnette also addressed the elephant in the room — whether or not there will be a second season of 13 Reasons Why — during their appearance.
“We really don’t [know],’ Minnette said. “I feel like the world’s going to know before we do if it happens!”
