Ah, young love.

As many back home deal with snow and chilly temperatures, Miley Cyrus and fiancé Liam Hemsworth warmed up with a Costa Rican vacation last week.

The star couple, looking relaxed and fit, cuddled up at sunset on Thursday after walking the shoreline on their beach trip, which was reportedly to celebrate Hemsworth's 23rd birthday on Jan. 13.

The couple, who were engaged last May – with Hemsworth presenting Cyrus, 20, with a 3½ carat vintage Neil Lane ring – traveled to Costa Rica with Hemsworth's older brother, Luke, his wife Samantha, and the couple's three children.



Cyrus has recently been in the studio recording new music while Hemsworth is filming Paranoia and The Hunger Games: Catching Fire.
