Believe it or not, there is another facet to Jake Paul’s personality that the world has yet to see.

The YouTube star-turned-pro boxer — who will face former UFC middleweight champion Anderson Silva on Saturday — is known for his outspoken tone and bold internet acts.

However, his girlfriend, Julia Rose says there is a somewhat softer side to “The Problem Child”.

“The real Jake, and I always tell him I hope one day he kinda shows that side of him, is so selfless and so giving and has one of the biggest hearts I’ve ever seen,” Rose told The Post in April at the Magic Hour Rooftop at Moxy Hotel Times Square, where she joined Paul in promoting the Katie Taylor–Amanda Serrano fight.

“I’m trying to pull it out of him a little more so he’s not afraid to show that side to the world, Jake’s a f–king amazing human being and that’s really it at the end of the day.”

Paul is unapologetic about taunting his opponents on social media — and frequently drags the wives and girlfriends of his rivals into storylines. He stole Floyd Mayweather’s hat off his head in the lead-up to Mayweather’s fight with Paul’s brother, Logan.

Rose declared that she “would 100 percent agree [that people don’t know the real Jake],” but she understands that he has a certain reputation to uphold in his line of work.

“I think it’s a super power that Jake has to play this character really well and do it in a way that gets people’s attention. He’s an entertainer at the end of the day,” Rose said.

In a separate interview, Serrano told The Post that she believes Paul is misunderstood, and that he the boxer is genuine in his intentions to promote females in boxing.

Paul is 5-0 in his professional boxing career. His fight with Silva on Saturday will mark the first time he will face a fighter with actual boxing experience.

Paul was previously scheduled to fight Hasim Rahman Jr. in August at Madison Square Garden, but the bout was cancelled due to a weight issue with Rahman.

“It’s tough, you know, watching anyone you love get into the ring,” Rose said. “It’s obviously nerve wracking. But it’s different when you watch how much they prepare and how passionate they are with training and dedicated to the sport itself.

“If I knew he was going in there with little preparation I’d be way nervous, but seeing how prepared he is, I think it calms my nerves at the end of the day,” Rose said.

Paul and Rose first met in 2019, when she portrayed his girlfriend in the music video for his song, “These Days.” 

Rose is a former reality star, who appeared on MTV dating show “Are You the One?” She said she is now focused on modeling and entrepreneurship.

“I’m back and forth from Puerto Rico and LA. Jake brought me out there, he’s permanently [living] there,” Rose said. “I fell in love with it… It’s calm and peaceful. There’s the beach and it’s good to just get away from it all.

“We like to go to the beach, swim, and hang in the sun. Jake is obviously in training most of the time, but it’s fun… At the end of a really chaotic day, to have a person that you can just be yourself, decompress and not feel the pressure of the outside world.”

Paul and Silva’s Showtime Sports PPV fight will take place at Desert Diamond Arena in Glendale, AZ.

The Arizona Boxing & MMA Commission agreed to let Silva fight during a special meeting Thursday night, after requiring the MMA legend to take extra medical exams a day earlier.

Silva raised concerns about his health last month when he told MMA Weekly in an interview that he was knocked out twice during his training camp.
