While on the show, Katherine explained her undying love for Lady Gaga (SAME GURL), and how she inspired her to learn the piano. Her biggest fan-girl moment happened not too long ago when Lady Gaga tweeted "Katherine <3".
But, the best part? When it happened Katherine was filming, so she didn't have her phone on her. When she finally looked at her phone, she had a bazillion messages and missed calls from her publicist, saying "Get on Twitter NOW!"
Her first thought? "Oh sh*t my nudes have leaked."
LUCKILY, no such thing happened, and even though she's joking about it, it's a sad reality that this was her first thought.
With the amount of celebrity nudes that have been leaked over the years, including Jennifer Lawrence, Miley Cyrus and Emma Watson, it's a shame that this is something to be expected now. #NotCool.
