Billie Eilish exited the gym on Monday with a joyful expression, having completed a successful workout session. 

The 20-year-old singer, known for ‘Ocean Eyes,’ sported a fashionable workout outfit, including carrying a pair of sturdy boots in the crооk of her arm. 

Recently marking the one-year anniversary of her album ‘Happier Than Ever,’ the acclaimed artist also delivered an impressive performance at the Hollywood Bowl last Friday.

During her workout, the award-winning singer opted for a sleeveless vintage black T-shirt to stay cool, paired with brown gym shorts. Complementing the ensemble, she wore comfortable blue sneakers with black ankle socks.

 Eilish styled her dark hair in a loose ponytail, and she carried a backpack over her shoulders, holding a pair of thick black boots and a large water bottle for hydration during her outing.
