The ITV talent show judge, 49, chatted with boxer AJ, 30, on her morning slot on Heart Radio – but the exchange left some feeling like she was enjoying herself a bit too much.
The two-time unified heavyweight champion had been spending his morning chatting on various radio shows to promote his partnership with Hugo Boss, but the conversation quickly took a flirtatious turn when it came time for AJ to jump on Heart.
AJ chatted to Amanda and her co-host Jamie Theakston about fighting fellow heavyweight Tyson Fury.
Amanda protectively gushed over the star’s good looks, threatening: “Look after that pretty face or I’ll kill him myself.”
AJ was seen giggling at Amanda’s compliment in a clip of his interview posted on social media.
Jamie tried to continue with the chat about the boxer’s future fight but couldn’t seem to get in on the conversation as the pair playfully flirted on the airwaves.
Radio presenter Amanda was seen in hysterics as Anthony beamed: “I just want to go back to Amanda’s compliment if you don’t mind.”
“Look after your face, darling,” the 49-year-old mum of two responded.
Jamie desperately attempted to get the interview back on track, goading the fighter: “Can you beat him?”
But Amanda was too quick to interject, enthusiastically shouting, “Of course he can!” before giggling that she “feels like his manager today”.
Good sport AJ joked: “I was just telling my manager he’s sacked and you’re now my manager.”
Amanda flashed her pearly white teeth once again as she giggled over her new position.
“Thank you! I’ll take less commission and I’ll do you’re ironing,” Amanda offered up to the athlete, who is almost 20 years her junior.
After the short interview drew to a close, listeners were quick to jump on social media to express their thoughts.
One simply said: “Wow, Amanda Holden has gone full creep this morning #AJ.”
While another wrote: “Amanda Holden creeping on Anthony Joshua on the radio this morning is cringey as hell. Two people worth turning the radio off for.”
Anthony also spent a few minutes with Roman Kemp over on Capital FM, where he let listeners in on a tidbit about his usually very private love life.
Amanda may have joined the rest of the UK’s singletons in disappointment as AJ revealed he’s been dating a mystery woman during lockdown.
In a made up game of “Heavyweight or Featherweight”, Roman asked the star to pick an easy or hard question for three categories.
When the “love” category came around, AJ chose the heavyweight question – never one to back down from a challenge.
He was asked: “What was the last date you went on and who was it with?”
Anthony confessed he’d been on “a nice walk” for around an hour and a half “when the weather was nice”.
Roman reminded him of the second half of the question, but AJ quickly backtracked and said “featherweight,” refusing to give up the mystery woman’s identity.
Back in May, Anthony admitted he would like to find love with “someone to grow with,” but is still searching for the perfect match.
The champion boxer has a four-year-old son, JJ, from a previous relationship, but still remains single.
Much of Joshua’s time is taken up by training and his dedication to boxing, as he works hard to defend his WBA, IBF, and WBO titles, but does still seem to find space in his busy schedule to date.
Tune into Capital Breakfast with Roman Kemp, weekdays from 6am – 10am across the UK.
