The smitten TOWIE star uploaded an image of his second child to Instagram on Wednesday afternoon (1 April) alongside the caption: "She looks so much like her beautiful mummy."
Dan and EastEnders actress Jacqueline welcomed Ella Selina, their first child together, in February 2015.
He's also dad to son Teddy, one, from a previous relationship.
Dan's picture came amid after Jacqueline spoke out in his defence yesterday, responding to claims made by Dan's ex-girlfriend, the mother of Teddy. She had claimed Dan was manipulative and controlling during their relationship. Audio recordings of phone conversations between them are also alleged to feature Dan being verbally abusive towards her.
Yesterday, Jac broke her silence, tweeting: "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 previously said of the phone calls:
"It has taken me a while to find the right words but I would like to say that I am truly sorry to anyone who was offended by what they heard. I am unable to talk about the difficulties with my current family situation but I am taking steps to resolve it to achieve the best outcome for my son. I am ashamed and embarrassed that I allowed myself to reach such a dark place that I behaved in a way that even I didn't recognise.
"While I acknowledge that there is absolutely no excuse for my deeply regrettable behaviour, I plead for some understanding that I had no intention of violence."
