Stone has recently made multiple trips to visit Garfield while he's in London starring in a stage revival of Angels In America, according to The Sun.
A source close to the two said, "Andrew’s feelings for Emma never softened and now they are growing close once again." They also revealed, "They have even been sneaking out of the back door holding hands."
Additionally, the source adds that "Emma spent some time in the U.K. earlier in the year shooting her new film The Favorite, but made a further trip to London when they have reconnected."
"There is a lot of history between them but they are both so busy. At the moment they are just seeing what happens," the source responded.
Stone and Garfield first met while working on The Amazing Spider-Man in 2012. They dated for several years, and also shot The Amazing Spider-Man 2 together on 2014.
By 2015, their relationship fizzled out and they went their separate ways.
It may not come as a surprise to some that the couple is potentially getting back together, as neither of them has been romantically linked to anyone else in a significant way since they initially split.
While Garfield is busy with Angels in America, Stone is busy herself with an upcoming Netflix series called Maniac, which she executive produces as well as stars in with her former Superbad co-star Jonah Hill.
