Ariana Grande on Bed Habits: ‘My grandmother encourages nude sleeping’

Songstress Ariana Grande has opened up about her bedtime habits and confessed that it's liberating to sleep in the nude.

During an interview with Us Weekly, the 'Break Free' beauty admitted that she tries to wear as little as possible when she goes to bed as it's something her grandmother suggested is a good idea:

"I sleep in very minimal clothing. My grandmother encourages nude sleeping."

She also revealed that she's a strict vegan and absolutely loves animals, adding that she is currently the owner of four pet dogs: "I have four pet dogs: Ophelia, Coco, Toulouse and Fawkes. I love animals more than I love most people. I'm a vegan as well."

The superstar, meanwhile, has just announced details of a full U.S. headlining tour that will kick off next year on February 25 in Kansas City, Missouri. The jaunt will come to an end on April 16 in Vancouver. She has also just been confirmed as the musical guest for the Saturday, September 27 episode of SNL (Saturday Night Live).
