10 Youngest Wrestlers To Ever Compete At WWE SummerSlam
2. Kelly Kelly
Four our runner-up, we return to the SummerSlam 2007 Divas Battle Royal and to The Extreme Exposé. Alongside Brooke and Layla, Kelly Kelly excited mid-2000s audiences with her dancing and occasional stripping, which is weird considering she was a teenager when she debuted. The Exposé were popular enough to earn a spot in the SummerSlam Battle Royal and Kelly - aged 20 years 7 months and 11 days - made history as the youngest woman to ever compete at SummerSlam.
In only her fifth match on WWE TV, Kelly lasted for a decent amount of time before being thrown out by Jillian Hall and eventual winner, Beth Phoenix. She was unsuccessful in becoming the number one contender to the Women's Championship, but Kelly winning this match had never been on the cards so very few people were upset or shocked.
Kelly's luck would change at her next SummerSlam in 2011; she successfully retained the Divas Championship over one of the women that eliminated her in 2007, Beth Phoenix. That might have felt good, but surely it wouldn't have come close to the time she competed on a major wrestling pay-per-view before she was even old enough to drink.
