Jacqueline – who is expecting her first baby with TOWIE's Dan Osborne – shared the scan photo alongside a 'gender reveal cake', which, when sliced into, reveals pink or blue sponge, indicating a girl or boy (no other colours exist in the world, OK?).
The photo was uploaded on Instagram with the message: "Twinkle twinkle little star how we wonder what you are? #pink or #blue."
Jacqueline hasn't revealed the outcome of the cake (as yet) – could there be a magazine deal in the pipeline?
The mum-to-be was celebrating doubly hard with the cake, as yesterday (Wednesday, October 1), Jacqueline won 'Sexiest Female' at the Inside Soap Awards.
Speaking at the bash, she told reporters: "It's quite nice to have that kind of label considering I'm pregnant, it's fabulous!"
Jacqueline announced her pregnancy in August, saying: "We're thrilled by our news."
