As break up rumors surrounding Miley Cyrus and Liam Hemsworth's relationship continue to grow, the "Hunger Games" star revealed that he enjoys working with co-star Amber Heard, who he shoots sex scenes with in his upcoming movie, "Paranoia."

"Intimate scenes are always pretty scary," he said. "[On set] you're being intimate with someone in front of a lot of people, and it's hard to let go and just be free in the scene."

"But Amber's such a great girl and so much fun to work with and she does a terrific job in this film."

Miley Cyrus and Liam Hemsworth break up rumors have been intensifying with the couple spending more time apart - the "We Can't Stop" star has been promoting her newest album, "BANGERZ," while the "Hunger Games" star has been filming several different pieces.

While Miley Cyrus confirmed the status of their engagement last month during an interview with "Good Morning America," speculation the couple might be splitting continued to grow after her little sister Noah told reporters the Hollywood couple hasn't started planning their wedding yet.

Miley Cyrus even visited Liam Hemsworth in Canada while he was shooting his newest film "Cutbank" late last month, but revealed later on that she's the only one making strides to keep the relationship alive.

There's no official word yet on the couple's engagement status.
