These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Les Yay Shipping: She has gotten tons and tons of that with former friend Demi Lovato, and the fall out they had in 2009 merely served to further fuel it. Now that they're back to being BFFs, this even gets better.
If you thought "Slow Down" was about slowing down a song, think again.
The last few seconds of the "Round And Round" video show one of the spies following Selena around holding on to a metal railing for dear life. His hand slips, the spy apparently falling to his offscreen death as Selena blows out a match.
The Woobie: Her being with Justin Bieber turned quite a few of Justin's fans to wish death on her for no reason other than their relationship infuriating them.
Also the fact that she later posted screenshots of texts from him being a complete prick to her after they broke up (circa the same time his house was subject to a DEA raid) including hounding her to get back with him, and sending her unsolicited pictures of his genitals.
