Lauren, 34, first shared a clip of Charles, 23, arms wrapped affectionately around his neck.
In the next upload, Charles showered her with kisses as Lauren declared him “the most beautiful boy I have ever seen”.
It was first revealed that the couple were dating last month when Lauren referred to the hunk as her “morning workout.”
The reality queen was careful to hide her face in the early stages of their romance, despite rumors they were seeing each other.
Charles then did his part to encourage dating rumors by sharing a photo from inside Lauren’s bedroom on his Instagram page.
The worker-turned-model hit the headlines last year when his brief affair with Katie Price went public.
The glamorous model was dating Kris Boyson at the time and had to tell her personal trainer that she cheated on young man Charles.
After Katie evacuated Charles back to Kris, her toyboy lover called her “lazy in bed.”
The glamorous model then reportedly retaliated by saying, “Bob the builder could have done a better job on his house,” a source told The Sun last year.
Lauren’s former boyfriends include prisoners Joey Morrison and Jake McLean and her ex-fiance Mark Wright, who is now married to Michelle Keegan.
A rep for Lauren previously said she and Charles were “just good friends” after it was reported that Katie Price had issued a warning to them.
Katie criticized Charles as “just wanting to be famous”.
She also urged Lauren to be careful not to let him into her life, The Sun reported.
An insider who spoke to the post revealed, “Katie is furious because she’s convinced Charles just wants to be famous and that’s why he’s dating Lauren. ”
“She said Lauren would have to be really careful not to let him into her life.
“She’s actually shocked that Lauren is considering dating him in the first place. “
