Selena visited Ellen's show on Friday's episode, and that's when the host asked her why she's not in Taylor Swift's squad like she is. Sel's response was cute, "I mean, I think you are. I would assume. You got the sparkles down." She was referring to Ellen's time on stage with Taylor during the 1989 World Tour.
Selena then said it helps you get into Tay's crew if you know how to bake, drink wine and talk about boys. "I can talk about boys, especially if I drink wine," Ellen, who's an out and proud lesbian, joked.
But when their conversation turned to why Selena loves Taylor. That's when she was startled by a man dressed as T-Swift, who popped out of a box right beside her.
Selena nearly freaked the eff out. Selena didn't really think it was too scary, though because she urged Ellen to "get her good" next time. Little did she know, however, that the next time would be just a few seconds later.
While discussing trick-or-treating with her little sister, a man dressed up as Frozen's Elsa snuck on stage and scared the living daylights out of Selena. "Oh my gosh! What the hell?!" she screamed.
