His 'worst habit'

Orlando's fiancee Katy Perry spilled that her partner has a bad habit of leaving used dental floss laying around.

The ‘Firework’ hitmaker is thankful that actor has fantastic oral hygiene and his "brilliant" pearly whites but had less kind words for his casual attitude to cleaning up after himself in the bathroom.

After being asked what bad habits her fiancé has, she told Heart radio: “Oh my God, he loves to floss, which thank God because some partners don’t and it’s disgusting and he has brilliant teeth.

“But he leaves the floss, everywhere! On the side of my bed, and in the car, and on the kitchen table, I’m like, ‘There are bins everywhere.'”
