Conor McGregor posts congratulatory message to Katie Taylor on Instagram

Last night saw Katie Taylor dominate yet another fight and retain her world titles in Boston.

Her professional record is now 11-0 and it's fair to say she looked unstoppable in last night's fight against Cindy Serrano.

Another famous Irish fighter was there to watch Katie — Conor McGregor visited her in her dressing room before the fight and the two shared a sweet moment.

After Katie's impressive win, Conor took to Instagram to sum up how everyone in Ireland feels about our number one boxer. McGregor also called for Taylor to be "guided fairly and correctly up that money tree".

What an honour to watch our very own @katie_t86 live tonight in Boston! This lady epitomises hard work, passion, drive, and laser like focus! A motivating inspiration! Congrats Katie and coach @rosstraining! Promoter Eddie Hearn and manager Brian Peters you both better be making sure our champion is looked after and guided fairly and correctly up that money tree as her activity is constant and consistent".

"This lady is an asset and should be treated as such. We are watching. Great work team Katie! #IrelandChampion".

After the fight, Taylor called out the sister of her opponent from last night — Amanda Serrano, who has become a world champion in six different weight classes.
