The TOWIE star fuelled speculation the wedding was off when she was spotted without her huge engagement ring at the NTA Awards on Wednesday night.
Speaking at the event, her ex-boyfriend James 'Arg' Argent also admitted, "I don't know if she's still engaged."
Now her spokesperson has confirmed to the Mail that the engagement is over.
It's not known if Gemma and 37-year-old Rami, who have been dating on-and-off since 2011, have also ended their relationship.

Following Rami's Christmas Day proposal, Gemma took to Twitter on Boxing Day to share her happy news and show off a picture of her diamond ring.
"Very excited to announce that I got engaged yesterday I am very very happy RamTech_ I love you best Xmas pudding x," she wrote next to a picture of her ring nestled in a Christmas pudding.
The couple have had a number of ups and downs in their romance. Last year, Gemma hit out on Twitter, seeming to suggest Rami had used her for her fame and money.

"Be careful girls when man uses you to gain fame and money and then when they can't get it they turn," she wrote.
"I'm usually a smart girl. I have been used for months in order for someone to gain fame. I saw it in the end.
"I will survive this and wait for a genuine person that doesnt want fame money and to destroy me!"
