Danny could now face consequences for his family's actions, as the ITV show's rules say no messages are allowed to be sent to camp mates.
His friends and family reportedly put together a message which read: "Love from Pufalump."
Danny is currently the fourth favourite at the bookmakers to win the show and was voted deputy camp leader on Wednesday's show.
An ITV source said that crew members saw it hovering in the sky with a banner on the back saying: "Danny Miller to win I’m A Celebrity."
A show source said: "It seemed like the idea was to fly over the castle in the hope Danny or a contestant would see it and pass on the message to boost his morale."
Danny jokingly admitted to having a crush on camp leader David Ginola, saying: "Sleeping next to the guy, I have 100% solidified my man crush on him."
During the show's time off air, after Storm Arwen saw Gwrych Castle evacuated, the stars were placed back into isolation with no way of contacting their loved ones.
But, family and friends are allowed to send in treats and letters to campmates, handed over by ITV during the series.
Other than that exceptional chapter in I'm a Celeb's history, the campmates aren't allowed any contact with the outside world.
