Although Dan is now seeing TOWIE co-star Lucy Mecklenburgh, he and his ex-girlfriend are having a child together.
Dan had been dating his ex for 12 months but they broke up before the Marbella TOWIE special was filmed - and before he and Lucy caught each others' eyes.
Confirming his baby news following a scan, Dan vowed to be a "great dad" to his unborn child.
He said: "I'm so excited to be a dad. Having seen the scan it now feels very real and even though I know it won't be easy, I can't wait to meet my little son or daughter.
"I know I'll be a great dad and will be there every step of the way."
It is thought that, although Dan's ex is maintaining her privacy, she has agreed for the baby to be referenced in future episodes of TOWIE.
Lucy has not mentioned Dan and his ex-girlfriend's pregnancy on her Twitter account.
