The former TOWIE star dated Jake for two years before they split in 2013. They rekindled their relationship earlier this year but so far there are no plans to wed just yet!
Lauren responded to the rumours via Twitter, saying: "Wonder what this wedding dress I've apparently chosen looks like then?! And hen do in Marbs?! Does make me laugh #SourceRubbish."
Well, that's told us then!
Lauren only confirmed her romance with Jake was back on in June, sharing an image of him on holiday with her in Abu Dhabi. She said at the time he'd whisked her off on a romantic trip abroad.
Things seem to be going from strength to strength for the couple as Lauren branded Jake her "soulmate" last month while wishing him a happy birthday.
She's also had his name tattooed on her wrist.
Ten reasons we want to be on TOWIE!
