'13 Reasons Why' cast get asked about season 2 in interview

Ellen brought 'Hannah Baker' to tears with this birthday surprise, and it's actually the most adorable thing EVER.

Katherine Langford and Dylan Minnette stopped by for a chat on The Ellen DeGeneres Show over the weekend, where Ellen decided to surprise Katherine with a little something for her 21st birthday.

Watch the clip above! (FYI it's at the end of the vid).

The 13 Reasons Why stars are downplaying any knowledge of that they might have about a possible season two for the popular Netflix show, with Dylan Minnette insisting "We don't know yet. We really don't."

Katherine Langford joined him as the new stars jumped on Ellen DeGeneres's couch for a chat about the series, and of course Ellen wants to know about season two. We all want to know!

Minnete told Ellen that he thinks he is so out of the loop that he won't even be told about a new season, he'll find out online: "I feel like the world's going to know before we do if it happens. I'll be online and be like, 'Oh, there's a second season.'"

Ellen also asked the pair about the moment they knew their show was a big deal, with Langford fan girling over a Tweet that Lady Gaga sent out last week with her name and a love heart.

Minnette realised when he went to Coachella the other week and everybody kept calling him Clay, asking him if there was going to be a new season, which is all everybody wants to know, apparently!
