Jennifer Lawrence is supposedly dating Nicholas Hoult...but maybe he should be careful?

After all, ther's a clear chemistry with costar Josh Hutcherson from "Hunger Games: Catching Fire"...and it seems there may be a romance also.

In a shocking new interview with HitFix at San Diego Comic-Con, Hutcherson confessed that the two are closer than some originally thought and that he misses his costar.

 "We long for each other so badly," Hutcherson, 20, said. "We do miss each other. We're both in different parts of the world filming and stuff, so it's hard to get to see each other."

Nicholas Hoult be damned, apparently.

The two will have to wait until September, when the final two Hunger Games films will be shot. "Mockingjay Part 1 and 2" will be shot then. Maybe, however, there will be some secret trysts around LA first?

They apparently had a lot of parties in LA while filming...that got hot and steamy.

"We were shooting long days and it was very physical, so we definitely needed to let loose and have a good time and we did that for sure," Hutcherson said.

Hutcherson also revealed details about his new role, saying "Peeta grows up a lot. I think his undying love for Katniss is still his main driving force for what he's doing and why he's doing it," he said.

Hutcherson added, "He really steps up in this movie and he kind of knows he has to fight harder than he did the last time, because more is on the line this time around."
