Miley Cyrus decided to keep it "casual" while relaxing at home.

The singer, 26, showed off her toned bikini body in a series of posts on Instagram stories which featured the "Black Mirror" star in a strappy black two-piece.

First, she snapped a photo of herself while lounging on a couch, using her hand to prop up her head. She captioned the photo, “keepin it casual." Then, she posed in front of a long mirror with an oversized blazer worn over her bikini with the caption, "Business as usual."

The revealing photos come just after Cyrus dropped a video for her single “Mother’s Daughter,” which is a new track off her EP "She Is Coming." The video sparked controversy for its HSFW content which features signs that read "virginity is a social construct" and "not an object."

The music video also featured Cyrus in a red latex suit with metal studs sewn into the crotch area, a woman breastfeeding her baby, and another woman's C-section scar.
