Just a day after releasing her surprise single [1], "Still Have Me," Demi Lovato [2] is "servin' lewks," as she said herself, in a bold outfit she shared on Instagram Thursday night. In the mirror selfie, the singer wore an emerald green blazer dress with padded shoulders and cuffed sleeves, which she paired with sky-high black heels and a Chanel Boy Bag. Smart and sexy at the same time, Demi's suited look complemented her fierce smoky eye and '60s-style half-up pony perfectly.

The retro vibes reminded fans, including Sarah Paulson of her character, Nurse Ratched [3], from the new Netflix series, as the asylum nurses are seen wearing tailored silk uniforms in a "surgical green" shade on the show, similar to that of Demi's dress. "Nurse Ratched looks good on yoooooou 💚💚💚💚💚," the Ratched actress commented on the singer's Instagram.

The post comes just a week after People first reported Demi had ended her engagement [4] to former fiancé Max Ehrich after only six months together. While Demi has yet to formally address the split, her new breakup anthem seemingly speaks to her feelings regarding the ending of their relationship.
