Confirming the news through their spokesperson, the couple say in a statement: “We’re thrilled by our news”.
The announcement comes just eight months after Dan welcomed his son Teddy in December.
“Becoming a father has been the most amazing thing to ever happen to me. I can’t believe I’m going to be dad again – I’m truly blessed,” Dan added.
A representative for EastEnders has also congratulated the mum-to-be, saying: “Everyone at EastEnders is thrilled for Jacqueline”, reports the Daily Mail.
The couple have been on/off for the past year, but 21-year-old Jacqueline confirmed their romance was back on in June when she posted a cosy picture of the pair cuddling on her Instagram page.
“There’s not one bad thing I could say about her … We enjoy each other’s company. She’s a really lovely girl,” TOWIE‘s Dan said of Jacqueline.
Meanwhile, Jacqueline, who plays Lauren Branning on the hit BBC soap, has admitted she’s a huge fan of her boyfriend’s famously ripped torso.
“I’m a fan of all his tattoos. He’s hot stuff,” she says.
Dan was thrilled after discovering his ex-girlfriend Megan was pregnant last year.
“I’m so excited to be a dad,” he said then. “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.”
Megan gave birth in December and Dan tweeted: “SOOO happy to let you all know that our little baby boy was born this morning! He’s perfect! Love him more than anything!!”
Dan has since kept his fans updated on his beloved son’s progress via social media, and gushed about the eight-month-old on Twitter just hours before announcing his baby news with Jacqueline.
Adding several pictures of Teddy, he wrote: “Most beautiful little boy in the world!! Seeing this little man smile and laugh is literally the best feeling in the world!”
Jacqueline’s pregnancy means she will need maternity leave next year. That means EastEnders have to find a way to write Lauren out of the soap for a while…or maybe permanently?
