Jennifer Lawrence and Nicholas Hoult broke up two years ago but now that they are back on the set to film the next installment of the "X-Men" franchise, and it seems as if the two are rekindling their romance.

The former couple sparked rumors last month when they were spotted out enjoying dinner with one another in Los Angeles.

Now that the "X Men: Days of Future Past" stars are filming the sequel up in Montreal the actors appear to be attached at the hip off set, according to OMG! Yahoo!

Lawrence, 22, and Hoult, 23 spent the weekend together, starting out at the Canadian Grand Prix on Saturday along with their co-star James McAvoy .

OMG! revealed that the trio happily posed for a picture with a member of the Caterham Formula 1 Team. Michael Fassbender and the director of the upcoming "X-Men" film, Bryan Singer were present for the racing festivities as well.

Later on that evening the former couple parted from the group to go see the HBO Boxing event at the Bell Centre.

The duo sat next to one another as they watched the fight and had a good time in each other's company.

A witness told OMG! Lawrence and Hoult enjoyed themselves "They were having a lot of fun together."

"They were into the fight, they would get up and cheer. They looked really cute together! They seemed flirty at times to me."

On Sunday night, the two headed back at the Bell Centre, this time around to attend The Rolling Stones concert.

As of lately the former lovebirds have been spending a lot of time together when the cameras are not rolling.

Last week the stars were spotted out with Lawrence's family taking a stroll around Montreal.

Sources told OMG! that they would not be shocked if the two eventually got back together.

"When they broke up in January it was hard for both of them, but amicable," the source revealed.

"Jennifer was busy with awards season, and Nicholas was all over promoting 'Warm Bodies.' They kept in touch."

A source from the "X-Men" set also spilled that even if the two are not filming a scene together, one will typically hang around set if the other is shooting.
