The reality TV star and model, 23, made the happy announcement on Twitter late on Friday night (9 January).
Dan wrote: "Can't keep it a secret anymore.. Me and @jacjossa are having a girl!"
Alongside the tweet, Dan posted a photo of himself and Jacqueline posing with the celebration cake they ate back in October to announce the sex of their unborn baby.
At the time, though, the couple teased us by sharing a black and white version of the photo, so we couldn't see the inside of the cake was pink!
Or Jacqueline's dress, for that matter!
On top of the cake, the wording read: "Twinkle twinkle little star, how we wonder what you are."
Fans were thrilled to hear the news, with one saying: "OH MY GOD!!!!!!!! A little princess I love this! Congratulations to you both xxxx."
Another shared our excitement when they posted: "Awhhhh congrats! Teddy can be a protective big brother."
Jacqueline, 22, is now in her third trimester of pregnancy, and no doubt busy shopping for cute girlie things for her first baby!
Dan has a son Teddy from a previous relationship.
Now we all await the birth of the baby with the best-looking genes in showbiz!
