Katy Perry has revealed some unusual facts about herself this week including that she always travels with a teddy bear and that she feels she has OCD.
The 'Teenage Dream' singer revealed a number of tidbits in a brand new interview with Us Weekly to help promote newly released album 'Prism' this week, while admitting she brushes her teeth up to six times a day and is known by friends to be a "hoarder".
"Everyone in my life seems to think I'm a hoarder, but if you ask me, I'm a collector," she explains.
Katy also revealed she is set to become an aunt sometime soon, as well as admitting she feels she has obsessive compulsive disorder.
"I'm so OCD that I wish the letters OCD were in alphabetical order, CDO," Katy added.
