Jennifer Lawrence and her boyfriend Nicholas Hoult have reunited on the set of the new X-Men: Days of Future movie in Canada.

The 'Silver Linings Playbook' star had broken up with the British in January 2013 after dating for two years.

But the pair seemed to have rekindled their romance, according to latest reports.

A source told Us Weekly: "They started the shoot in April as friends, and then one day they just started kissing. One thing led to another and they hooked up. All her old feelings came rushing back. Now they're fully back on."

Lawrence, 22 and Hoult, 23, have been spotted together in Montreal last month and sources say they have been inseparable since.

They attended the annual Canadian Grand Prix race together on June 10. They were also spotted having dinner together at The Little Door restaurant in Los Angeles in April.

The pair met two years ago on the set of the first X-Men: First Class prequel and embarked on a romantic relationship almost immediately. Lawrence stars as Mystique and Hoult takes on the role of The Beast - both blue mutants.

Lawrence won an Academy Award for Best Actress this year for her role in Silver Linings Playbook. She starred alongside Bradley Cooper, sparking rumors that the onscreen couple was dating.

Lawrence will be joining her 'Hunger Games: Catching Fire' co-star Josh Hutcherson on stage at the Comic-Con San Diego 2013 on Saturday to present the first full-length trailer of the second installment of the series.

Hoult is best known for his roles in 2002 hit film 'About a Boy,' where he starred alongside Hugh Grant as 12-year-old boy Marcus.
