TOWIE star Billie, who is expecting her first child with fiancé Greg Shepherd, joined Sam in the car yesterday (16 June) and together they posed for a selfie.
The girls, who looked chic and summery in sunglasses, pulled their best pouts before Billie posted the snap on Instagram. Commenting, she said: "Sisters .... Car #selfie."
Billie is pregnant with a baby girl and is due to give birth to her this month. But after playing around on her mobile phone, the excited mum-to-be is wondering whether she'll arrive early!
The glowing reality star used a question and answer texting service yesterday, which said the baby will arrive on Thursday (19 June)!
Tweeting her sister in excitement, Billie said: "Eeeeek @samanthafaiers an early girl!? #auntysam."
Whenever her little girl decides to make an appearance, Billie's swish Mulberry hospital bag is packed and ready by the door.
Earlier this month, Sam also gave fans a tour of Billie and Greg's gorgeous nursery. All that is missing is the baby - but it won't be long!
