Ferne had flown to the Spanish island for just one day due to work commitments and was delighted when BFF Billie pitched up.
Former TOWIE co-star Billie was staying nearby, as she is currently filming sister Sam's new reality show Sam Faiers: The Mummy Diaries, so she surprised Ferne with a night out.
Sharing a picture of herself with bestie on Instagram, Ferne told fans: "Highlight of my 24-hours in #mallorca was bumping into my BESTIE. I literally screamed when she surprised me last night."
Although they both found fame on TOWIE, Ferne and Billie go waaaay back.
The girls were childhood school pals and have been there for each other through thick and thin.
