The 'E.T.' singer's confessed to a mucky habit.
Katy Perry has revealed she is partial to hanging out in dirty washing with hubby Russell Brand.
The singer says that sometimes the only way the couple can avoid the paparazzi is to be secretly shipped out of hotels in grubby containers.
"We go to great lengths for our privacy," Katy explained.
"Even if it means riding in the back of the laundry truck to get out of a place unnoticed, we will go for it."
Katy Perry is currently on her US tour but is back in the UK for more gigs in October.
