The Irish star has never shied away from a challenge and won her first world title in just her seventh fight. Since then she has gone onto become a two-weight world champion as well as becoming the undisputed women's champion at 135lbs.

Katie Taylor's undisputed glory at MSG; June 1, 2019
Fighting on another Anthony Joshua undercard, Katie Taylor bid for undisputed women's lightweight glory when she faced Belgium's Delfine Persoon.
What followed was a contest fit for the historic Madison Square Garden with Persoon applying constant pressure from the opening bell and forcing Taylor onto the back foot.
While Taylor was looking to showcase her boxing skills, she found this difficult with Persoon applying rough tactics in the clinch. This made for a thrilling fight with both women cancelling each other out whenever an opportunity seemed to have presented itself.
The fight went the distance and it was Taylor who was awarded the win via majority decision with two judges scoring the fight 96-94 and the other declaring the contest a 95-95 draw.
The pair would meet in an entertaining rematch one year later.
Katie Taylor becomes a two-weight champion; November 2, 2019
After becoming the undisputed women's lightweight champion against Delfine Persoon, Katie Taylor decided to move up in weight to face the WBO women's super lightweight champion Christina Linardatou.
Linardatou came out on the front foot, but from round two, Taylor found her rythm and gained control of the contest.
There was a scare in round eight when a right hand from Linardatou rocked Taylor who then opted to revert back to her boxing skills instead of opting for an all guns blazing approach.
This proved to be the right decision with Taylor being declared the winner by unanimous decision with scores of 97-93, 97-93 and 96-94.
