Katherine Langford is a big Lady Gaga fan. Not only does the Australian actress have Gaga to thank for her piano skills, but as it turns out, a recent tweet from the singer actually made Katherine fear that her nude photos had been leaked online. During a stop on The Tonight Show on Friday night, the 13 Reasons Why star, who doesn't have a Twitter account, revealed the hilarious reaction she had when she got a tweet from Gaga herself. "My publicist is like, 'Katherine, you need to go onto Twitter right now.' And I was like, 'Sh*t, my nudes have leaked.'" Fortunately, the scenario turned out to be much better than she had anticipated.
