Last week, Miley Cyrus
was photographed without her engagement ring
. On Sunday, her fiancé Liam Hemsworth
was snapped missing something else.
The tough and toned actor, 23, who was on vacation in his native Australia, took a swim in the ocean with friends back home, then strolled down the beach without his shirt.
Hemsworth was also photographed enjoying a beverage
Down Under with pals on Saturday. Reps have not responded to requests for comment on the couple's status.
A source told PEOPLE that the Hunger Games
star flew to Australia to "have a break"
from Cyrus, 20.
"Miley is still upset with Liam," a source told PEOPLE on Friday after the 20-year-old star stepped out sans engagement ring. "She took the ring off to make him mad."
