Saraya-Jade Bevis (ring name Paige) does indeed have gauges, you can see one in this photo:
She's not the only wrestler to have piercings, although this can be pretty risky when taking part in a full contact sport as they can be pulled or ripped out!
Wrestling with gauges and piercings
Gauges and piercings in general are pretty popular these days, especially so within the wrestling community where it's all about show, appearance and glamour... which is why most wrestlers these days sport tattoos of some sort.
However, gauges and piercings are a slightly separate matter, as there are some healthy & safety considerations to bear in mind.
As Paige shows, it is not impossible to get into the ring with gauges... and wrestlers like CM Punk and R-Truth are known for sporting body modifications, as are Lita and other WWE Divas
What you may notice with all these athletes is that, when they step into the ring, their body jewellery is always minimal.
Hooped earrings and items that are likely to get accidentally caught are strictly forbidden - while studs, gauges and well-fitting lip-rings are more acceptable.
