Megan Fox, aged 36, has acknowledged that she was 'in love' with Shia LaBeouf while discussing their 'completely romantic' relationship.

It has become evident that the chemistry between the two wasn't confined to the set of Transformers: Revenge of the Fallen, as they were co-stars.

Despite Fox's highly-publicised whirlwind romance with fiancé Machine Gun Kelly, it is apparent that he was not the only flame in her life.

The star of Jennifer's Body made an appearance on an episode of Watch What Happens Live with Andy Cohen, during which they played Plead The Fifth - a game in which one can only decline to answer one of Andy's numerous questions.

He asked "How would you characterize your relationship?"

After taking a moment to consider whether to decline the question or not, the actor ultimately revealed what actually occurred between the two when the cameras weren't rolling.

"I mean, I would confirm that it was romantic," she admitted.

She went on to reveal: "I love him, I have never been really quiet about that, I love him."

The host, keen to obtain additional details, followed up by asking if the relationship was simply an on-set romance that did not progress beyond that.

Smiling to herself, Fox replied: "Yeah," before agreeing that it was a 'showmance'."

The news has been confirmed not only by Fox but also by others.

LaBeouf had told Details magazine in 2011: "Look, you're on the set for six months, with someone who's rooting to be attracted to you, and you're rooting to be attracted to them."

The Nymphomaniac star added: "I never understood the separation of work and life in that situation.

"But the time I spent with Megan was our own thing, and I think you can see the chemistry onscreen."

There is no doubt that you can.

Fans were eager to express their reactions to the significant disclosure.

One social media user wrote: "I always thought that Shia and Megan were meant for each other."

"Shia and Megan belong together. There I said it," posted another.

A third prophesied: "I wouldn't be shocked if they get together again one day. I mean it's prob going to happen again."

A fourth added: "They had great chemistry in the movie. Not surprised they'd probably go for each other on real life."

"It's not surprising that they had feelings for each other," echoed a final person, ️but hey maybe they'll reconnect in the future."

Only the passage of time will reveal.
