Girl group Fifth Harmony celebrated Simon Cowell’s 54th birthday by toilet papering their X-Factor mentor’s Beverly Hills home Monday morning.
The girls didn’t keep their antics a secret as they also hung up a large sign that read, “Happy 87th Birthday Simon!! Love, Fifth Harmony.”
Simon Cowell formed Fifth Harmony during the second season of The X-Factor last year by bringing Ally Brooke Hernandez, Normani Kordei Hamilton, Dinah Jane Hansen, Camila Cabello and Lauren Jauregui together after they all failed to move on in the competition as soloists. Like The X-Factor‘s other success story One Direction, Fifth Harmony failed to win the competition but were signed by Cowell anyways.
The girl band will join Cowell’s fellow X-Factor judge Demi Lovato as she hits the road for her Neon Lights tour next year.
