Did you spot this?
Last week, eagle eyed Taylor Swift fans spotted her in Selena Gomez's video for Bad Liar. If you missed that you can check it out HERE.
Now, she's been spotted in another one of Selena's creations - 13 Reasons Why.
If you haven't noticed her, we don't blame you. It's a very minature appearance that is easily missed. All with thanks to a Tumblr post that has gone viral, fans of T-Swizzle have seen her.
During the scene where Tyler and Sheri are chatting in the hall of Liberty High, there's a poster in the background which turns out to be the cover of Taylor's album 1989.
We're not sure if Selena did that on purpose, but we wouldn't be surprised. The pair are best pals.
