The outspoken gal made the shock revelation just hours after launching her dating site for people with tattoos.
Speaking to her 69,000 followers, Jemma wrote: "I'd like to confirm me and @CharlotteDawsx are officially a couple. Thank you for all your love and support."
Despite not adding to the post, Charlotte decided to fuel rumours by retweeting the message.
Jemma Lucy shows off her tats and boobs in these smokin' hot pictures.
The last time we checked Jemma was busy chewing Stephen Bear's face off.
The news was met with a mixed response from fans who couldn't work out if Jemma was being serous or just having a laugh.
While another added: "Aww happy for youse bet youse are never bored 2 funny girls haha.[sic]"

However, a third questioned: "Are you really? I thought you had a boyfriend"
Openly bisexual Jemma has previously confirmed she has enjoyed relationships with both boys and girls.
Back in June she even released a seriously steamy video of her passionately kissing Geordie Shore gal Marnie Simpson.
While earlier this week she was spotted constantly locking lips with Charlotte during a messy night on the town.
