An eyewitness told E! News that a group of female fans spotted Hemsworth, 23, walking down Jonson Street in New South Wales' Byron Bay earlier this week and immediately started shrieking and running toward him.
The actor managed to duck into a nearby shop, but was later forced to reemerge into the street, where the fans were excitedly waiting.
"He looked a bit angry with all the girls around him," the onlooker said. One day later, Hemsworth was spotted spending time with brother Chris Hemsworth, sister-in-law Elsa Pataky and their baby daughter India Rose on Friday, March 8.
The LOL actress opted not to wear her diamond engagement ring for her night out on the town, the second time in as many days. Cyrus was first spotted without her ring on Wednesday, March 6, as she headed to her recording studio in an all-black outfit without her bauble, leading to murmurs of a troubled engagement.
