The pair looked good together in their matching denim, white trainers and black combo.
Aspiring music artist Junior topped off his look with a black furry hat, while the brunette looked stunning in a sleek half-up hairdo with natural make-up.
The couple, who have launched a joint TikTok account, posed with props and sat together for pictures in the fake electric chair.
A source told The Sun: “Junior’s already introduced Jasmine to his dad and step-mum Emily.
“It was important that they approve of her, but he’s already smitten.
“The relationship has been kept on the down-low so far, but telling his fans he was committed was a big step.”
Model mum Katie spoke about age-gap relationships on her podcast with her sister Sophie.
She said: “Isn’t it funny when your kids get older and they get in relationships and you meet their girlfriends and boyfriends as they’re adults, she’s an adult.”
Katie, who is in a relationship with MAFS star JJ Slater, who is 13 years younger than her, continued: “They’re not like young kids at school.
“‘What’s weird is she’s 23 [24] and he’s 18, see? You can always get an age gap in relationships. As you get older an age gap doesn’t matter.”
Dad Peter, 51, is married to doctor Emily MacDonagh, 35, and share a significant age gap.
Emily gave birth to their first daughter Amelia in January 2014, and in 2015, almost three years to the day of their first public date, the couple tied the knot in a lavish wedding at Mamhead House in Exeter.
Their second baby, Theo, followed just over a year later, in November 2016 and they welcomed baby Arabella in April 2024.
