Gemma confided in best pal Bobby Norris at the Summer Solstice party that she had given Rami the boot over the way he treated her.
Bursting into tears, Gemma revealed: "I've had a terrible day. Rami's said something really bad to me and I've had to break up with him."
Just at the beginning of this month, viewers saw businessman Rami romantically surprise Gemma in Marbella, but she revealed that it wasn't at all paradise for the couple.
When Bobby asked if it was the final straw, Gemma replied: "Final straw, this is it. I had trouble with him in Marbella, he's been saying to me I'm not sexy and that if I want him I've got to keep working harder.
"When I go to put my arms around him he goes, 'get off me, get off me, I've just come in from work, give me some space'."
Gemma then went on to reveal that her confidence has hit an all time low. She said: "I've been lonely in my life before and I don't want to go back to being lonely."
As Bobby attempted to comfort her, Gemma added: "My confidence is low at the minute."
Gemma and Rami, who met on the ITV2 show last year, have hit a rocky patch before and in May.
After the show, Gemma retweeted messages of support from viewers. One fan said: "He will regret the way he has treated you!! Hold your head up high and move on sweetie."
Meanwhile another wrote, "Gemma keep your head held high. Happiness will come your way because you are a lovely lady. Don't change for anyone!! Smile!"
Gemma later said: "Thank you all for your amazing tweets I will be OK time is a healer x."
