To celebrate her love for Saturdays, Miley Cyrus took to Instagram July 30 and posted a photo wearing a black bikini with matching shorts.

Fans quickly noticed how thin the singer appeared in the photo, and flooded her comments section asking if everything was okay in her personal life.

The star's personal life has seemingly been going well, especially in the romance department. She's been spending most of her time with beau Liam Hemsworth, and recently got a tattoo in his honor. We're hoping there isn't trouble in paradise, because she was spotted rocking her engagement ring from the actor just last week.
