It looks like Simon Cowell's marked his 54th birthday by cleaning the toilet paper off his Beverly Hills mansion.
So, who would have the guts to Toilet Paper Simon's pad?
TMZ claims the culprits are the ladies from Fifth Harmony, the girl band Simon signed to a record deal after they performed on "X Factor" last season.
Besides the toilet paper, the gals also hung a banner that reads, "Happy 87th Birthday Simon!"
