Lauren posted the snap on Instagram in the early hours of today (2 April) but it is believed to have been taken on a night out last month.
Reality star Lauren wore the same see-through striped shirt while visiting London's Mahiki in February after going under the knife and getting a boob job.
The top features a zip down the front, meaning Lauren is able to reveal her boosted cleavage in all its glory!
Meanwhile, Lauren also took to Twitter last night and posted a cryptic message. It read: "If she doesn't get jealous when someone has your attention .. It's because someone has hers."
Lauren posted a kissing emojicon next to the tweet. Could this mean there's a new romance on the cards for her?
Spill the beans, Lauren!
Since quitting TOWIE in 2012, the bubbly blonde has appeared on Dancing On Ice and has been focusing on her tanning range.
But more recently, Lauren has hit the music studio with rapper Fugative to record her debut single!
