Fox recently confirmed that she dated LaBeouf while filming the 2007 movie.
Megan Fox shared a gem of a throwback photo on Wednesday.
The 32-year-old actress and now-mom of three surprised fans with a photo of her former Transformers co-star, Shia LaBeouf, on the set of the 2007 film. The former Disney Channel star is adorably fresh faced in the pic, in which he tries his best to match Fox's memorable pose checking out the engine of a car.
"Once upon a time 13 summers ago ?," Fox wrote alongside the image of LaBeouf, who was no more than 20 when the photo was taken. The two also starred together in the 2009 sequel, Transformers: Revenge of the Fallen, but Fox dropped out of the third movie in the franchise, Dark of the Moon, after a public feud with director Michael Bay.
Fox, who married Brian Austin Green in 2010, confirmed during her November appearance on Watch What Happens Live With Andy Cohen that she and LaBeouf dated while filming Transformers in 2006.
"I mean, I would confirm that it was romantic," she said. "I love him. I've never been really quiet about that. I love him."
"So it was an on-set romance that didn't go anywhere afterward?" Cohen pressed.
"Yeah," she replied.
