Jack Fincham and Emily Atack were reportedly caught "snogging" at the National Television Awards on Tuesday night.
It comes just days after Dani Dyer's ex-boyfriend announced the birth of his daughter, Blossom, who he shares with long-time friend Casey Ranger.
Sources claim that Emily and Jack were huddled up to one another while whispering into one another's ears at the plush awards.
It's said that they were giggling together and at one point, it appeared the two were embracing each other during an intimate kiss.
Speaking to The Sun, a source said: "After kissing, Jack told her, 'we can't be seen together', and they quickly went off elsewhere."
While a second source went on to say: "They'd retreated into a corner by some stairs in a bid not to be spotted but couldn't keep their hands off each other.
"Jack kept pulling her closer and was touching the back of her neck. They seemed to want to keep it discreet as they left separately."
Emily has been single since she split from film producer Rob Jowers in September after the pair dated for six months.
However, Jack has previously dated Dani Dyer after the pair met on Love Island before he fathered a child with Casey.
Speaking about his involvement with Casey, he said that their "whirlwind" romance didn't work out but they intend to co-parent their daughter due to the fact they have known each other for so long.
He said: "Because we've known each other a long time it just works, we've known each other for years since I was 17."
Jack also vowed to tone down his wilder side after he became a party animal following his Love Island success.
A representative for Emily and Jack has been approached for comment.
