Jacqueline, 21, is expecting her first baby with boyfriend and TOWIE star Dan Osborne and took a selfie while still in bed this morning (4 September).
The actress even popped the hood up on her rather festive reindeer all-in-one before taking the snap in the mirror at home.
Sharing it on Instagram, Jacqueline commented: "It's too early for clothes!! Onsie it is!!"
Mum-to-be Jacqueline announced her pregnancy last month, saying she and boyfriend Dan are "thrilled" by the news.
Although the tot will be Jacqueline's first child, it is second time around for Dan, who welcomed his son Teddy with his ex-girlfriend last December.
Last week, the couple headed off on a baby moon to Egypt and Jacqueline bared her tiny bump for the first time while balancing an ice cube in her tummy button.
No wonder she's now swapped her summer clothes for a onesie, it must be freezing here in comparison to the Middle East!
