I'm 100% pregnant, Towie's Gemma Collins tells Big Brother housemate

Celebrity Big Brother contestant Gemma Collins told a fellow housemate she is "100% pregnant" - but it later turned out to be a false alarm.

Viewers will see the former The Only Way Is Essex personality tell American reality star Tiffany Pollard on Friday night's show that she suspects she is pregnant.

But a spokesman for Channel 5 said: "Gemma believed she was pregnant but later found out this wasn't the case."

Two weeks ago, Strictly Come Dancing professional dancer Kristina Rihanoff announced she was pregnant on the show.

In a conversation with Pollard as the pair did the washing-up, Collins said: "I'm 100% pregnant. I know it, I know it, I know it. I'm excited but I'm nervous as well. I need a test."

She continued: "Listen, my belly, I know my belly when it's fat. I'm used to it. But this is a rock hard lump. I'm having a baby, I know I am, I'm scared. I definitely am. I can feel it in me."

When Pollard, 34, seemed unconvinced, Collins, also 34, told her: Look, it's there."

Pollard conceded: "If it's hard down there, it's a sign."

Collins has been dating Stephen Mortimer since they met at the Sugar Hut nightclub in Brentwood, Essex, last year.

But Mortimer will not be present when his girlfriend leaves the Celebrity Big Brother house, as he handed himself in to police on Tuesday.

He had previously spent two years in prison for grievous bodily harm, and was released on condition that he lives at his sister's home.

He breached the terms by living with Collins and is now back in jail for a further 28-day stint.

Celebrity Big Brother's Bit On The Side panellist and comedian Vikki Stone was not convinced by news of the pregnancy, telling viewers: "She's a reality star. She knows how to make scenes."
