Rumour has it that the pair (who are both currently battling it out to become Lord Alan Sugar's business partner) had "major chemistry" while filming for The Apprentice, with Elle and Mergim finally hooking up once the show's eleventh series had wrapped.
According to The Sun, Elle, 21, and Mergim, 23, finally gave into their feelings for each other when both attended a party hosted by their fellow contestant Natalie Dean.
A source told the paper, the pair were flirting at the bash, before heading off together to have sex.
"Tension had been building between them," they said. "When filming finished and booze was involved, they allowed their feelings to develop.
"They kept poking fun at each other and acting like teenagers, then snuck away from the group and had sex. [The] next morning they had sore heads and it seems regret crept in."
While the pair may have hooked up, the source added that a romance between Elle and Mergim is "unlikely", even if they have kept in touch.
News of the pair's fling came to light after the Sunday Mirror revealed viewers were set to see a romance blossom on screen.
Without giving away the identities of the stars involved, a show insider had claimed: "Two of the candidates had massive chemistry right from the start.
"They got together in the house and had sex, but it wasn't a one off - they really liked each other and have got together since filming too."
Onscreen we are still in the early stages of the competition and so far there has been no hint of romance. This week, the candidates are instructed to sell products at The London Pet Show.
