The "We Can't Stop" singer posted a photo wearing a playful tee which read: "Don't Let Those M----r F-----s Kill Our Vibe," while biting into a pancake she held with her manicured nails.
Tagged in the photo was friend Katy Weaver, who also Instagrammed a video of the pancake party, captioning the vid: "Makin pancakes @mileycyrus's house after a funnnnn night of Lucy in the sky videos and Love couches #lovemoneyparty."
The singer was hospitalized for more than a week because of a severe allergic reaction to the antibiotic Cephalexin, her rep announced in a statement; the medication had been prescribed for a sinus infection.
A source confirms to Us Weekly now that she's out of the hospital, the 21-year-old is preparing to return to the road for the European leg of her Bangerz tour.
"She's doing much better," the insider tells Us. "She had to get it all out of her system. It hit her hard."
