The 22-year-old and Dan, 23, announced their happy news this week, and Jacqueline was quick to take to social media to gush over him.
Sharing a sweet snap of her in the pool with Dan, Jacqueline simply wrote: “My fiancé.”
Dan, who is the father of Jacqueline’s daughter Ella, broke the news on Twitter on Monday evening.
The former TOWIE star wrote: “She said YES!!! I am the luckiest man in the world to be marrying the woman of my dreams @jacquelineMjos !!! [sic].”
Dan and his wife-to-be recently enjoyed a break away, and made us all very jealous with their sun kissed selfies.
In one, Dan is kissing Jac on the lips as she gazes into the camera. “She’s just everything,” he added alongside it.
It’s been a turbulent year for Jacqueline and Dan, who is also father to son Teddy from his relationship with teacher Megan Tomlin.
Their relationship was rocked when audio clips leaked which allegedly heard Dan threatening to stab Megan.
Although the clips resulted in him being dropped from ITVBe’s The Only Way Is Essex, Dan has apologised for his actions, insisting ‘there are always two sides to every story’.
