The 16-year-old sensation, also known as The Nuke, has taken the internet by storm and even a professional wrestling giant is interested in him.
After the finale, WWE invited him to attend their show at the O2 Arena in London on April 19.
“Incredible racing @LuketheNuke180,” the company said on X via the official WWE UK account.
“We hear #WrestleMania 33 inspired @BBCR1's entrance music, so you're officially invited to WWE's @TheO2 in London on April 19.
“We might even be able to get the @Pitbull 'green light' for you!”

Littler, from Runcorn, became an overnight sensation as the tournament's youngest ever finalist, despite finishing second behind Alexandra Palace's Luke Humphreys.
The darts star's habit of eating a kebab after every match has already earned him a lifetime supply of kebab meat from Iceland, and now WWE is taking notice.
On his way to the final, Littler announced that he had chosen Pitbull's hit song Greenlight as his exit song following his participation at WrestleMania 33 in 2017.
The event featured a live performance by Pitbull and Flo Rida, whose music was the main theme of the event.
“It was from WrestleMania 33 in 2017. I went there [to Orlando, Florida] with my father; “It was unbelievable,” he told BBC Radio 1.
Although his fan base in WWE has diminished over the past seven years, it is still something he holds close to his heart.
“It's fair to say I don't like fighting anymore,” he added. “I think I'm over it now, but it's just a WrestleMania experience and I learned the song from it.” [Pitbull].'
If he joins O2, he wouldn't be the first star to break into the wrestling business.
