Liam Hemsworth and Gabriella Brooks Beg the Question, How Can One Couple Be So Good-Looking?

Liam Hemsworth and Gabriella Brooks are still going strong! On Monday, the couple steamed up the beach when they went for a morning swim in Byron Bay, Australia. The 30-year-old actor showed off his ripped abs (seriously, you could grate cheese on those!) in orange swim trunks, while the 23-year-old model slipped into a sexy strapless bikini. Liam and Gabriella seemed to be in good spirits as they splashed around in the water and enjoyed some quality time together.

The pair first sparked dating rumors this past December following Liam's split from Miley Cyrus. Since then, the two have been spotted on a series of dates in both LA and their native Australia, and Gabriella even seems pretty tight with Liam's family. It sounds like things are getting pretty serious! See more of Liam and Gabriella's beach day ahead.
