The Essex star shared an image of himself and Jacqueline to Instagram over the weekend alongside the caption: "She's so beautiful. Inside and out. I'm so damn lucky."
Dan and Jacqueline began dating in August 2013 after meeting at an Essex nightclub. At the time, Dan's ex-girlfriend Megan was pregnant with his son Teddy, born December 2013.
Then in February this year, he and Jacqueline, 22, welcomed their daughter Ella Selina Osborne.
Dan, 23, also shared a new picture of Ella to Instagram over the weekend, saying: "Our perfect little girl smiling away. Two months old today!"
Another snap was shared to Jacqueline's account.
It hasn't been a drama-free year for the couple. In March, EastEnders actress Jacqueline spoke out to defend Dan following allegations he'd been verbally abusive to his ex-partner.
"I can assure you I wouldn't stand by a man capable of everything dan has been made out to be, he is my best friend, boyfriend and he is a brilliant father, above all else, I just want to clear up, he has never once been violent or even shown signs towards me at all.
"People selling stories on him, show one side to a story, but people around dan know the whole truth, and you would all be shocked.
"I am 100 percent not saying what Daniel has said was right or okay, but people make mistakes when on dark places, and it's something that we sorted out privately not in front of the whole world, it's something he has apologised for and is embarrassed about."
Dan was forced to apologise the same month after leaked audio recordings surfaced of conversations between him and the ex.
