13 Reasons Why actress Katherine Langford is high in demand these days and she finally has given her first solo interview on a talk show!

The 21-year-old actress sat down for an appearance on The Tonight Show Starring Jimmy Fallon on Friday night (May 12) in New York City.

Katherine opened up about her love for Lady Gaga and the hilarious reaction she had when she got a tweet from the singer.

“I think she sort of knows who I am, which is a weird thing to say. I did this interview and they were like, ‘Who is your favorite artist?’ And I was like, ‘Lady Gaga.’ And a fan tweeted it at her and she reposted it and wrote Katherine with a love heart,” Katherine said.

“The thing is though, I don’t have Twitter. So the way I found out was, I was shooting a film. Nighttime. Didn’t have my phone. Came back to my trailer and I kid you not, there were like five messages, three missed calls,” Katherine continued. “My publicist is like, ‘Katherine, you need to go onto Twitter right now.’ And I was like, ‘Sh-t, my nudes have leaked.’”

Thankfully, nothing has leaked, but she has gotten an invitation to visit Gaga backstage on the upcoming Joanne tour!

FYI: Katherine is wearing a Dion Lee dress, Jimmy Choo shoes, and Irene Neuwirth jewelry.

He added, “We don’t get it here [in England], so I didn’t grow up watching it. But I think as soon as you’re in America or doing music, you kind of know that it’s a big deal. So we’re lucky enough to be on it while in the band, and I feel lucky to be going on again. I’m happy to be going back on there.”
