YAY - it's a Taylor fest! And not a cat to be seen! She does make reference to them in the Ellen video...
As for her fears themselves, they're not exactly "irrational". They should give her the fear, especially as she had to total hum of the Piper Chapman's off her and would no doubt be made someone's 'Dandy-lion' prison wife post quick (if you've no idea what we're talking about, you need to get yourself on to Netflix). Also, sea urchins are spikey and therefore not to be trifled with.
In case you can't view the video for whatever reason, here's a rough transcript of what Taylor says about her fear of being imprisoned:
"I'm scared of getting framed. So many people would frame me and they could frame you for any crime that you could go to jail for. Look at me, I wouldn't survive in jail. I think it comes from the fact that I could open up my phone, I could look at my phone and see any headline written about me at anytime and it could be the most ridiculous untrue thing. So, I think the dream and the nightmare of being framed comes from, I could do nothing wrong, I could sit in my house with the cats all day and somehow there could be an article about me buying a house in a place I've never been or dating a guy I've never met. But then you take it a step further and in nightmare world it's being framed for murder."
24 short hours later, Taylor was then on Kimmel, where she was presented with the music booker who "threw her out of" the show when she requested to perform, aged 14. So it's the music bookers' turn to get turfed ourra the building. No, like, properly turfed out. Then Taylor and Jimmy discuss that time he set a twerking girl on fire. Fin.
