Jake Paul: Hawk Tuah girl slammed by Nick Kyrgios after making surprise appearance at YouTube star's boxing win over Mike Perry

Nick Kyrgios has aimed a dig at viral sensation 'Hawk Tuah' girl Hailey Welch after she made an appearance at Jake Paul's boxing win over Mike Perry.

Welch, who has gone viral over the past month for graphically describing her sexual exploits in a now-famous interview, was seen ringside as the YouTuber-turned-boxer claimed his 10th scalp in boxing in impressive fashion by beating Perry.

The 21-year-old has rubbed shoulders with famous faces ever since exploding on the internet, and was seen hanging out with NBA legend Shaquille O'Neal a fortnight ago.

But tennis star Kyrgios, 29, has taken aim at the American's appearance at the big fight. 

Taking to X - formerly known as Twitter - Kyrgios tweeted: 'No correlation between fame and actually being decent at something anymore,' along with a laughing emoji.

Welch, who has cashed in on her infamy with a trademark for 'Hawk Tuah' hats, t-shirts and more, broke her silence after her viral video rocketed to fame.

Speaking to Brianna Lapaglia on the Plan Bri Uncut podcast, the 21-year-old said fans had even offered up to $600 to spit in a jar for them.

But Welch - whose unusual spelling of her Christian name has been confirmed by DailyMail.com - added she was hesitant to be 'Hawk Tuah' girl forever. 

She also revealed she has now quit her factory job and hired management after the clip of her explaining how to 'make a man go crazy in bed' during a Nashville street video racked up more than three million views on YouTube after airing last month.

When asked what her parents think of the comment, Welch replied: 'They think it's so funny... they never know what's gonna come out of my mouth.'
