The openly bisexual star, who found fame on Love Island in 2018, is said to be doing reality TV gal Demi Sims.
According to reports, the pair met during filming of E4 hit Celebs Go Dating and struck up a close bond.
A source told The Sun Online: “Megan and Demi met on the show and have been dating ever since.
“It’s really serious. They like each other a lot and it’s the real deal.”
Megan and Demi’s series of Celebs Go Dating is yet to air on TV, but it’s thought that their fling won’t be highlighted on the programme.
The duo were seen getting cosy on Wednesday night at the ITV’s summer party.
Dressed in a frontless leopard jumpsuit, the Essex gal made sure all eyes were on her.
Putting her naked chest on show, the starlet sent imaginations into overdrive as she left the bash hand in hand with Demi.
Previously talking about her sexuality, Megan said: “I first fell in love with a girl when I was 16, but it wasn’t even in a sexual way.
“I never saw her just in that way, but we’d like hang out, and one thing led to another.
“We would do everything together. I found her more and more attractive, and not even the way she looked, just like the way she was in general.
“I just feel like I have a deeper connection with women.”
A rep for Demi and Megan has been contacted by Daily Star Online for comment.
