On the other hand, there's Becky Lynch, the reigning RAW Women's Champion who won the first Women's main event in WrestleMania history to win the title and has become arguably the most popular women's wrestler in recent history.
Appearing together earlier this week at Stomping Grounds, the pair have been officially public with their relationship for a while now, and it'll be interesting to see what the future holds for the duo, both in and out of the ring.
