The TOWIE stars posted a snap, which appeared to show Chloe, 31, with a baby bump, which she and Elliott, 33, were resting their hands on.
Immediately fans commented on the photo, asking if there was another TOWIE baby on the way.
While Chloe and Elliott haven't commented on the rumour, her rep has revealed the truth.
According to heat, Chloe's agent said she's not expecting and it was just the dress.
Chloe and Elliott both have children from previous relationships, but last year he admitted they wouldn't rule out having more.
He told OK!: "I'd get married again if I met the right girl. Marriage is a beautiful thing. Would I have kids again? Yes."
Despite the fact Chloe and Elliott called time on their relationship at the end of the last series of The Only Way Is Essex, viewers saw them reunite during the Christmas special.
Chloe was distraught at the idea of Elliott moving on with someone else, resulting in him asking her to spend Christmas with him.
While there's no baby bump in their festive snaps (sob) the couple do look very loved-up!
