Are on-and-off former lovers Jennifer Lawrence and Nicholas Hoult back together yet again?

A recent snap shared by director Bryan Singer on Instagram showed him with the good-looking couple. However, rather than outing a reunion romance, the image was evidence of the actors' return to Singer's set for yet another round of Marvel adventures, this time for "X-Men: Apocalypse."

"Production continues on 20th Century Fox's summer 2016 mutant ensemble, 'X-Men: Apocalypse,' and director Bryan Singer revealed on Instagram that actors Nicholas Hoult and Jennifer Lawrence have arrived on the set of the upcoming sequel," ComingSoon said.

"Lawrence and Hoult play Mystique and Beast in a cast that also includes James McAvoy as Professor Charles Xavier and Michael Fassbender as Magneto along with the return of Rose Byrne as Moira MacTaggert, Evan Peters as Quicksilver, Lucas Till as Havok and newcomers Alexandra Shipp as Storm, Ben Hardy as Angel, Tye Sheridan as Cyclops, Sophie Turner as Jean Grey, Lana Condor as Jubilee G, and Olivia Munn as Psylocke," the site went on to say.

Villain Apocalypse will be played by Oscar Isaac, who will be seen in "Star Wars: The Force Awakens" as Poe Dameron later this year.

The upcoming "X-Men" installment will be the last in the trilogy that began with 2011's "X-Men: First Class." It will arrive in theaters on May 27, 2016.

While the snap the "X-Men" director shared may please fans of the franchise, it may also spark speculations over a revival of Jen and Nicholas' erstwhile romance.

It can be recalled that it was during the production of the first film that the two fell in love and cultivated a relationship, as MailOnline noted. They later split in 2013 and reunited by the time "X-Men: Days of Future Past" dropped in theaters.

Will they rekindle their old chemistry in the making of "X-Men: Apocalypse"? What do you think?

It's worth noting, however, that in the previous installments, both came to the set single and available. This time, Jen has rocker Chris Martin for a boyfriend while Nicholas is rumored to be dating Dianna Agron - a report that has not been confirmed.

Meanwhile, Bryan has been updating behind-the-scenes goings on through photos posted on his social media account. He had previously shared one of actor James McAvoy in the makeup chair as bald-headed Professor Charles Xavier.

In the wake of these updates, it won't be surprising to hear spoilers of the film to start making the rounds in cyberspace and continue rolling until the film arrives in theaters.
