We've all seen 13 Reasons Why. We've all obsessed, analysed, and cried over and over and over for it... but did you miss this HUGE detail?!
'Cos we did.
Last week, Selena Gomez released her music video for "Bad Liar" and a perceptive fan noticed that her BFF Taylor Swift made a cameo in it... well, it looks like Selena has a habit of asking her friend to make cameo's, because she was also in the show 13RW.
It's a major "blink and you'll miss it" moment, but it's there.
Tumblr user notes that Tay makes a brief appearance in Episode 10 of the series.
Tyler is talking to Sheri in the hallway of Liberty High, and there is a poster in the background.
If you pay close attention, you'll see that it's Taylor's album, 1989.
