EastEnders actress Jacqueline accompanied Dan to the tattoo parlour and took a picture as he got their daughter's name inked on his ribs.
The TOWIE star already has his son Teddy's moniker etched on his body and Ella's will now sit underneath.
In Jacqueline's photograph, Dan can be seen biting into a pillow as the tattooist gets to work. Commenting on the snap, the soap star has told fans how much she likes his new body art!
She said: "Currently in @ininkwetrusttattoo watching @danosborneofficial get his tattoo!! Ouch!! LOVE IT!"
Dan, meanwhile, has also posted a snap of himself and his tattoo artist, however he is yet to reveal the final work. Come on, Dan, give us a peek!
On 15 February, Jacqueline gave birth to Ella with Dan by her side and the couple later announced the news on Twitter.
Dan told his followers: "So so so so happy to tell you all!! Our baby girl Ella arrived yesterday evening, @jacquelineMjos done SO well, proud of you. I love you."
Since then, Ella has been pictured having cuddles with Dan's TOWIE co-star Danielle Armstrong and yesterday, Jacqeuline told fans how she was herself enjoying cuddles with her "scrummy baby girl."
Ella is Jacqueline's first child, while Dan became a dad for the first time to Teddy in December 2013. He shares his son with his ex-girlfriend.
On Wednesday night's episode of TOWIE, Dan was shown talking about Ella and Teddy with his co-stars.
He told them: "When I have both at the same time… Teddy still gets up in the night as well! With the baby, all she's doing is sleeping all the time, feeding and pooing at the minute."
Jacqueline and Dan: from meeting to baby!
