It's Toddlers and Tiaras: Celebrity Edition!
Before spray tans and dirty dances were required to win, stars like Britney Spears and Justin Timberlake got gussied up to strut their stuff in kiddie pageants.
Spears, now 30, first danced on stage at age 3 and won loads of pageant trophies, which are now housed in a museum in Kentwood, Louisiana. "I found out what I'm supposed to do at an early age," Spears has said.
Her ex-boyfriend Timberlake, now 31, "won six trophies" at the 1992 International Supreme King contest in Nashville, according to his grandmother Sadie Bomar.
Other stars who competed in pageants include Katy Perry, Blake Shelton and Demi Lovato. To see which other celebs showed off their impressive talents at an early age, check out Us Weekly's gallery now!
