Pregnant Billie has now passed her baby's due date and her friends and family are waiting with baited breathe for the new arrival.
In last night's episode of TOWIE (6 July), Billie was seen chatting to Gemma and Jessica Wright while showing them the tiny clothes she has ready for her daughter.
Suddenly, Billie held her stomach and doubled over, saying: "Oh my God, I've got a really bad pain in my belly."
Gemma then squealed (and looked like she was ready to call an ambulance), saying: "Are you joking me?! Are you going into labour?!"
As Billie and Jessica dissolved into fits of giggles, Gemma asked: "Is this a setup or something? Billie! My heart was going 'boo boom boo boom!'"
Although it was quite funny, the mum-to-be took to Twitter following the scene and tweeted: "He he he sorry @missgemcollins #TOWIE xxx." Naughty, Billie!
Billie is now officially overdue and is trying every trick in the book to bring on her labour.
Last week, sister Sam revealed that Billie had tried drinking raspberry leaf tea, which is an old wives' tale, and this weekend the star has been on a long walk.
Sharing some pictures of her trip around the park yesterday, Billie said: "Out for a nice long walk ... Get this baby moving .. #overdue."
It can't be much longer...surely?!
