Jack Fincham has been snapped sharing a smooch with a student two weeks before going Instagram official with girlfriend Connie O'Hara.
28-year-old Jack, who won Love Island in 2018 with then-girlfriend Dani Dyer, is seen with 17-year-old Lucy-Mae Georgiou at a Tenerife bar on July 18.
In the snaps - obtained by MailOnline - the pair lock lips, while another shows Jack with his arm around the pretty blonde as they posed for another photo.
A source told the publication that Lucy had 'no idea' Jack could be involved with anyone else as he acted like a single man.
"She only became aware of Connie after he posted the photo," they caimed.
The source also alleged that Jack offered to take Lucy out on the town back in London.
"He told Lucy the moment they met he thought she was a 'little sort'.
"She flew home the next day, by which point Jack had already messaged her calling her 'baby' and asking her plans for the following Friday," they claimed.
Mirror Online has reached out to Jack's rep for comment.
A spokesperson for Jack told MailOnline: "Jack was unaware of Lucy being 17 as the drinking age to enter bars in the Canary Islands is 18 years of age."
Earlier this week, Jack shared a cosy photo on his Instagram as he went public with with new girlfriend Connie O'Hara.
The cosy snap prompted some fans to question if the pair were engaged as Connie was sporting a huge diamond sparkler on her finger.
Jack was swamped with questions, but denied the rumours and confirmed he and Connie are not engaged to be married.
It's been a busy year for the reality star who welcomed his first daughter Blossom into the world this year.
Jack dropped the bombshell news in January this year and weeks later revealed the baby's mother is his friend Casey Ranger, with whom he enjoyed a brief romantic relationship.
The former pen salesman first rocketed to fame in 2018, as a contestant on Love Island where he immediately coupled up with Dani Dyer - who recently announced she was expecting her first baby with boyfriend Sammy Kimmence.
The pair quickly solidified their fan favourite status and went on to take the top spot.
Having dated for nearly a year outside the villa, they called time on their relationship in 2019.
