The former TOWIE star has told her Celebrity Big Brother housemate Tiffany Pollard that she's convinced she's expecting a baby as her stomach feels strange.
In a clip aired on Big Brother's Bit On The Side, she became upset as she told Tiffany: "I am 100 per cent pregnant. I know it. I know it. I know I am. I am excited but nervous as well."
"You have to a get a test," advised Tiff.
"I know my belly when I'm fat, I'm used to it, but this is something different," continued Gemma. "I am having a baby. I know I am. I'm scared."
Gemma then became tearful, so Tiffany tried to comfort her.
"Calm down, oh Gemma..."
"I definitely am. I can feel it in me," said Gemma, placing her hand on her stomach.
"You need to get a test," said Tiffany. "If it's hard down there it's another sign. That's how it starts."
