Dan Osborne, 23, and Jacqueline Jossa, 21, who have been officially dating for several months, confirmed their happy baby news on Friday 15th August.
In a statement released by Dan's management, he said: “We are thrilled by our news. Becoming a father has been the most amazing thing to ever happen to me. I can’t believe I’m going to be a Dad again – I’m truly blessed.”

A representative for EastEnders has also congratulated the mum-to-be, saying: "Everyone at EastEnders is thrilled for Jacqueline."
But how will her pregnancy affect Lauren Branning's storyline? We've taken a look at her character's current arc - and taken a look at some of the possibilities…
- Lauren Branning goes to prison
According to our timeline, Jacqueline Jossa will be giving birth sometime around February 2015 - just in time for the show's 30th anniversary celebrations and the conclusion to the 'who killed Lucy Beale?' mystery. Does that mean Lauren could be heading to prison for the murder of her BFF?
Judging by her role as amateur sleuth in previous episodes - and her insistence that ex-boyfriend Jake Stone was the killer - this seems unlikely. But, y'know, it IS Albert Square - anything can happen!
- Lauren Branning returns to rehab
Lauren Branning has had difficulties with drink in the past, battling her many demons with a little help from a vodka bottle - so perhaps the identity of Lucy Beale's killer could be what drives her back onto the path of self-destruction once again. Does this mean someone close to her - possibly Peter Beale or sister Abi - could be the culprit?
3) Lauren Branning becomes pregnant
We know she's going to sleep with Hot Dean (aka Shirley's son, Dean Wicks), so perhaps an unplanned pregnancy could be the result? It could be just the thing to make Dean take responsibility for his actions - but, then again, it would drive a wedge between Lauren and Peter Beale forever.

Unless, of course, it turns out to be his baby…
- Lauren Branning goes to visit mum Tanya

Tanya (Jo Joyner) conveniently left Albert Square in June 2013 - meaning there is somewhere off-screen for Lauren to go stay for a while until her dramatic reappearance once Jac's maternity leave is up.
- Lauren Branning could be killed (although we really hope not!)
We saw it happen in Coronation Street with Michelle Keegan's character Tina McIntyre - could EastEnders bosses have something similar in mind for Lauren Branning?
