The cute pictures suggest that his current girlfriend Jacqueline Jossa, 22, has finally met Teddy.
In interview earlier this year, Dan, 23, confessed that EastEnders star Jacqueline, who gave birth to Ella in February, hadn't yet met his son from his previous relationship with teacher Megan Tomlin.
But Jacqueline can be spotted in the background of Ella's bunny costume picture.
Dan followed up his bunny pictures with another of Teddy, hinting that he spent Easter with both of his children.
On Good Friday he posted a heartwarming snap seemingly showing the moment Teddy and Ella met for the first time.
He wrote: "ABSOLUTELY PRICELESS #mybabies"
Big brother Teddy looked happy to be hugging his baby sister, but Ella seemed more than a bit confused!
Dan's quality time with his children comes after two audio clips were published by The Sun, allegedly hearing him threatening 22-year-old Megan.
