Los Angeles: Actor Liam Hemsworth is reportedly dating his "Independence Day: Resurgence" co-star Maika Monroe.
The 25-year-old "The Hunger Games" star got cozy with Monroe, 22, at a party thrown by director Roland Emmerich, reported Us Weekly Magazine.
"His hand was on her butt as she was grinding into him and they were getting cozy at the bar," a source said.
The party included guests such as Vivica A Fox, Bill Pullman, and Lance Bass. "Liam was draped all over her. It was so PDA and in-your-face," the source added. The rumoured pair however have not made anything official yet.
"They're not official. But their chemistry is ridiculous," an insider said. Hemsworth and Monroe were earlier spotted grabbing refreshments in Malibu. "Independence Day: Resurgence" is scheduled to release in June 2016.
