Not only is Jennifer Lawrence’s acting career heating up -- apparently, so is her love life.

According to a new report from Us Weekly, the 22-year-old “Hunger Games: Catching Fire” star reconnected with her former boyfriend, 23-year-old actor Nicholas Hoult, while working on the film “X-Men: Days of Future Past” in Vancouver. The pair, who are co-stars in the sci-fi flick, are rumored to be officially back together after months of working side-by-side as lovers on-screen.

“They started the shoot in April as friends,” a source said. “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.”

The twosome was last spotted publicly together while attending the annual Canadian Grand Prix race in Montreal in June 10. According to the Daily Mail, the duo appeared comfortable around each other, posing for pictures and smiling while joined by their “X-Men” co-star, James McAvoy, 34.

Rumors that the former couple was planning to rekindle a romance sparked after the pair was spotted dining at the Little Door restaurant in Los Angeles in April. An unidentified source revealed to Us Weekly in June that the duo was not officially an item but working toward dating again after ending their two-year relationship in early 2013 due to issues with long distance and hectic filming schedules.

“They frequent each other’s trailers, and they always eat lunch together,” the source said. “It’s just a friendship now, though they’re getting a lot closer.”

Lawrence is scheduled to make her first public appearance following news of ther alleged reconciliation on Saturday at Comic-Con International 2013: San Diego. The actress will be joined by her “Catching Fire” co-star Josh Hutcherson on stage to present the first full-length theatrical trailer of the second installment in the four-film series.
