The former TOWIE star won immunity on Friday night's live show in the latest task, which will see each housemate battling for immunity from the next eviction across the weekend.
Housemates were told to stand behind a music box and wind the box up.
The housemate who uncovered the gold mask won immunity.
That was Gemma.
Gemma had been up for eviction tonight and #GetGemmaOut was trending on Twitter, but it was Ex on the Beach star Megan McKenna went home instead.
Some viewers took to Twitter to suggest it was a fix - which Rylan said it was NOT!
On Celebrity Big Brother's Bit On The Side, he said before everyone "started piping up on Twitter" there was no fix happening. He explained every housemate was asked to choose a music box at random and we all saw them enter the room and pick their box, so they couldn't have known Gemma would have chosen the winning one.
Emma Willis agreed, saying: "Everyone is going to say we fixed it! It's the series you couldn't have written. It really is. She baffles me, Gemma. Because she goes, 'Get me out of this house' and she calls producers all sorts of names, very bad ones, and she doesn't want to be there, or she says she doesn't want to be there and has these strops and tantrums, then she wins immunity and looks so happy that I'm like, 'What is going on?!'"
That's gotta be a fix, Gemma being immune! #CBB— Caitlyn [PB] (@caitlyn_niven) January 22, 2016
