Miley Cyrus is finding her chakra in paradise. On a recent vacation to Costa Rica with fiance Liam Hemsworth, his brother Chris Hemsworth and wife Elsa Pataky and other in-laws, the 20-year-old singer actress hit the beach in a bikini. While her fiance and his brother were snapped surfing, the Hannah Montana star preferred a more mellow form of exercise: Yoga.

In a slew of snapshots taken in the surf and sand Jan. 21, Cyrus displayed her taut, toned physique in a tiny black two-piece (later changing into a sports top) as she showed of her flexibility and master-level yoga moves including the "downward dog" and other classic poses.

The "Party in the U.S.A." singer, predictably, shared her serene state of mind during the trip via Twitter. "Bliss is unchanged by gain or loss," she wrote Jan. 21. "Para para paradise.. . Rare to get a moment to thank the universe for all my blessings in the form of yoga in a place like this.'

Cyrus showed plenty skin as well on the March cover of Cosmopolitan mag -- wearing a white blazer and low-cut white pants but no bra or shirt beneath. Inside, she counted her sexy fiance as the greatest source of contentment these days.

"Number one is my relationship with Liam," she said. "That's what I feel the most confident in because you never know . . . I'll literally look at him and be like 'You are hot, dear god!'"
