The 21-year-old star said: "I love snuggling up in bed and watching 'Orange Is the New Black' [while] being on
Macys.com or
SaksFifthAvenue.com . But I also love going to stores. That's more dangerous though, because I will buy everything and use nothing."
Ariana is known for her trademark ponytail, but thinks everyone should feel comfortable to experiment more.
She told PEOPLE magazine: "We're all different, so I think, 'Do whatever the hell you want!' Everyone should be able to express themselves with hair, make-up, fashion, art music, and it should all be accepted - and celebrated."
Asked what her spirit animal is, she said: "It's a seahorse because they're so little and cute, and because I love water."
The brunette beauty recently released her debut fragrance, Ari, and claims her brother, Frankie Grande, is a huge fan.
She said: "My brother wears it. It's for everyone.
"My favourite note in the fragrance is marshmallow. It's so good! I don't eat them often, though, because I'm vegan, and the vegan ones are not as tasty as the regular ones I ate when I was younger."
