The British beauty was shooting a campaign for Madonna's Material Girl clothing line when she collapsed.
Images from the set show a woozy Ora attempting to hold herself up on a car, wearing leather ankle boots and a skin-tight dress in 90-degree weather.
Ora was carted off on a stretcher to a waiting ambulance and treated for "heat exhaustion and dehydration" at Miami's Mount Sinai Hospital. "She was discharged and is fine," Dr. David Farcy, chairman of emergency, said in a statement.
The Roc Nation singer, known for the single "R.I.P.," announced her deal with Madonna's clothing line in June.
She has yet to release her own statement on yesterday's health scare.
