The reality TV starlet, who famously dated Michelle Keegan's hubby Mark Wright for a decade, logged into her official Instagram page before uploading the cheeky belfie.
Rocking a cheese-wire style thong, Lauren zoomed in on her backside as she snapped away.
Pushing out her rump, the Essex gal dared to bare as she covered her backside in baby oil before uploading the shot.
Keen to use the snap to make money rather than simply be X-rated for the sake of it, Lauren encouraged fans to go check out her OnlyFans page.
Lauren, 34, wrote: "Are you a part of my only fans? Don’t miss out on this," she signed off the post with some suggestive emojis.
Earlier this year Lauren insisted to new mag she hasn't had implants put into her backside to make it rounder.
She said: "I've always been thick set and I've always had a big bum. That's the way it is.
"Feel it if you want! I’ve not had implants."
Going further, Lauren also shut down claims she's secretly had a Brazilian bum lift.
A Brazilian bum lift is when fat is removed from other parts of the body and injected into the backside to give it a larger, rounder appearance.
She insisted to the glossy: "No, I've just got a big a**e! Feel free to do any X-rays or scans or whatever you need to do to prove it.
"Fat transfers don't last. You need to keep getting them redone and I'd be forever under the knife if that were the case!
"I had lipo and sculpting three years ago and that was it. My bum goes up and down with my weight."
Lauren recently confirmed she is dating Katie Price's ex Charles Drury.
Daily Star Online revealed how the tradesman turned online stripper is open to having kids with Lauren one day.
Replying to a fan on an Instagram snap, who said Lauren is hell-bent on marriage and kids, Charles said: "She might want those things as do I and when the time's right who knows, they might happen.
"I'm very content in life right now."
Not stopping there, he gushed: "Age means nothing when you meet someone with a beautiful soul that makes you happy and brings nothing but positivity to your life.
"I think I'll be keeping Lauren Goodger around me for a very long time."
He later added: "When you find a good one, got to keep hold of them."
