"Hunger Games" co-stars Jennifer Lawrence and Liam Hemsworth are rumored to be growing closer, after years of heavy back and forth flirting.

OK Magazine reports the onscreen chemistry between the stars has long been off the charts. Now they appear ready to give their connection a try in the real world.

"Anyone who's spent virtually any time around them can see that they have real feelings for each other," a source said. "The chemistry you see in their movies is real, and now they can finally act on it."

The two 25-year-olds have starred together in four blockbuster installments in the film series. With the series wrapping up, word is they are now more open to the prospect of a romantic relationship because work is finally out of the way.

Reports are the two recently hung out, after Lawrence told Vogue Magazine she spends most Saturday nights at home because "guys are mean to her."

Sources indicate her relationship with Hemsworth seems to work well because he knew her long before all the fame and isn't affected by the nonstop attention she now attracts.

During their recent worldwide press tour to promote the latest episode of "Hunger Games," many fans indicated Lawrence has never looked more appealing.

"She's not dressing just for the cameras," a source said. "She's dressing for Liam. Her hemlines are rising, her necklines are plunging and he's definitely noticed."

Lawrence recently raved to reporters about how Hemsworth stacks up in her view.

"Liam is the most wonderful, lovable, family-oriented, sweet, hilarious guy," she said. "I guess the biggest surprise is that I would never expect a man this good-looking to be my best friend."

Rumors are Lawrence has already started spending nights at Hemsworth's home, and he's already met her parents,

A source added that Lawrence's parents are thrilled at the prospect of their relationship.
