Kelly Monaco and pro partner Val Chmerkovskiy are dominating Dancing With the Stars Season 15 All-Stars, but many fans are wondering when Kelly initially competed (and dominated!) DWTS.

Kelly was DWTS’ first champion: She competed in and won Season 1 back in 2005. Back then, Kelly competed with dance pro Alec Mazo.

Dancing With the Stars airs Mondays and Tuesdays on ABC.
