The Australian actor, 23, was spotted leaving the Los Angeles airport in sunglasses and a gray hoodie after being out of the U.S. for three weeks, and reportedly headed straight to his fiancée's house. He "seemed rested and relaxed" despite coming off a 13-hour flight, says a source.

The actor then flew to the Philippines this week, where he debuted a scruffy new look

Cyrus, meanwhile, had her ring back on in Twitter photos
