The 24-year-old sent a couple of cryptic messages, and fans immediately concluded she was with child.
TOWIE star Lydia wrote: “After a slightly stressful morning I am finally in my car. Literally the most exciting but nerve wracking day ever.
“This is my excited/scared face. Watch this space. All will be revealed Monday.”
Lyd’s mum Debbie probably didn’t help things. She posted: “Wishing my @LydiaRoseBright all the best today. One of the most memorable days of your life. #goodluck #deepbreaths.”
Unsurprisingly James Argent’s girlfriend was flooded with messages speculating pregnancy.
But it wasn’t long before Lydia noticed the comments and quickly cleared things up.
She wrote: “OMG just reading all your messages from today’s Instagram post.
“Sorry for the confusion guys but I’m not pregnant.”
Lydia and Arg are currently in Dubai with fellow The Only Way Is Essex couple Georgia Kousoulou and Tommy Mallet.
She took to Instagram today to share a photo of the gorgeous foursome, writing: “Group pic. Last night Dubai Nobu. Photo bombed by the shark.”
