Sometimes the best way through is with something—or someone—new. Which is why Liam Hemsworth’s girlfriend Gabriella Brooks is so different from Miley Cyrus, the Australian actor’s ex. Liam’s new lady is also an Aussie, and when she’s not busy going on dates with her 30-year-old beau, she’s off modeling for runway and print campaigns. And according to a source with HollywoodLife, Liam thinks his 23-year-old girlfriend a real “breath of fresh air” compared to Miley.
