Jennifer Lawrence and Nicholas Hoult arrived together at the X-Men: Days of Future Past wrap party Aug. 18 in Montreal, Canada, adding fuel to rumors that they are once again dating.

The Oscar-winner wore a short yellow skirt and a transparent black tank as she held on to her co-star's arm. Hoult kept it simple in a T-shirt and button down. The Silver Linings Playbook actress also signed autographs for fans as the actors walked through the city on their way to the party.

The 22-year-old actress and Hoult, 23, reportedly broke up in January after being together for two years. They met on set of X-Men First Class back in 2011 and reunited while filming the movie's sequel. The two were said to have spent a lot of time together in between shooting and often ate lunch together, a source told Us Weekly in June.

Rumors of their reconciliation ignited back in April when they dined at the Little Door in West Hollywood, Calif. That photo can be viewed here. Two months later they were also spotted hanging out at the Canadian Grand Prix in Montreal.

A romantic reunion won't be easy, Hoult explained to The Daily Beast in a February interview. He talked about why it's difficult to make relationships work in the film industry, especially as a young actor whose career is taking off.

"It's tricky, because you're all over the place," he said. "We were shooting Mad Max: Fury Road for seven months in Namibia, so you're never really in one place, and when you are, they're strange places that are difficult to get to. I wouldn't change it, because you're very fortunate to travel, meet new people, and embark on these new experiences, but it's not great for that side of things."

X-Men: Days of Future Past comes to U.S. theaters on May 23, 2014.
