Shields is arguably the pound-for-pound No 1 in women's boxing having won two Olympic gold medals before compiling a perfect 10-0 pro record. However the 'GWOAT' has now set her sights on YouTuber Paul to show him how it feels to step in the ring with a real boxer.
"I, Claressa Shields, will whoop Jake Paul's ass," the American told TMZ Sports. "He can come in the ring weighing 180lb and I will come weighing 168 and I will beat the s**t out of him."
Shields was speaking in the aftermath of Paul's brutal KO defeat of Nate Robinson on the undercard of the Mike Tyson vs Roy Jones. That moved Paul's pro record to 2-0 but his opponents have been a fellow YouTuber and a former NBA player - the kind of fights which Shields claims are making a "mockery" of her sport.
"Jake Paul is making his money, he's doing his thing, but stay away from us real fighters," said the 25-year-old.
"And anybody out there that says, 'Oh, Jake Paul will destroy her because she's a woman'... I'm the greatest woman!
"So, no, Jake Paul won't do nothing with me - and if he thinks he can, he can come see me."
Shields told TMZ that she actually wants a real fight, not just a sparring session (and would donate her purse to the water crisis in her hometown of Flint, Michigan).
Although clearly no US boxing board would sanction a contest between a male fighter and a female fighter. However Shields let it be known that anyone who would give the 23-year-old Paul an edge because of his gender, does not understand the sport.
"I've been boxing for 14 years, two Olympics, but they would still give Jake Paul the nod because he's a man," she added. "And it's like: you guys don't know nothing."
Good job nobody asked Claressa what she makes of Jake's older brother, Logan Paul, fighting Floyd Mayweather in a February exhibition bout.
We're not sure whether she'd pour scorn on the whole card... or ask if she can fight the younger Paul on the undercard.
