#2 Rhea Ripley - 22 years old
Rhea Ripley, the former and inaugural NXT UK Women's Champion –– is the second-youngest active in-ring WWE Superstar currently competing in the company.
Ripley performs in the NXT UK brand where she became the youngest and the first-ever champion on the women's roster. She originally began wrestling at the age of 17 in 2013. She signed with WWE in 2017 and competed in the first Mae Young Classic before moving to NXT and finally settling in NXT UK.
#1 Xia Brookside - 20 years old
And last, but not least, we have current NXT UK performer Xia Brookside. Brookside wrestled for several indie promotions before taking part in the 2018 Mae Young Classic tournament. What you might not know is that she is the daughter of NXT trainer, Robbie Brookside.
Xia took part in a tournament to crown the inaugural NXT UK Women's Champion but was unsuccessful. At the age of 20, Xia is currently the youngest Superstar in WWE. Having a youngster like her in the company and in NXT UK is a good thing because NXT UK is a brand that is still growing and there's no doubt that she will grow with it.
She will also get to learn a lot of things from her fellow wrestlers and perhaps another shot or even an NXT UK Women's Championship reign could be in store for her.
