In August, Jacqueline announced she is expecting her first child with boyfriend and TOWIE star Dan Osborne.
Soon after hearing Jacqueline's happy news, Lorna said she was shocked her friend was soon-to-be a mummy - but not quite as shocked as Jacqueline herself!
Although, she does think Jacqueline and Dan's baby "is going to be beautiful!". Oh, we think so too!!
Speaking to Reveal the Inside Soap Awards last night (1 October), Lorna said: "I can't get over the fact that she's pregnant!"
Lorna and Jacqueline - who won Sexiest Female at the awards bash - have grown close after playing sisters on the BBC soap for the last four years (Jacqueline's character Lauren was previously played by Madeline Duggan).
Speaking about her onscreen sibling, Lorna said she "wouldn't pick anyone else to play her sister", but now the star is pregnant, what's in store for her character Lauren?
When asked if she thought Jacqueline's preganancy would be mirrored for Lauren in the show, a wishful Lorna suggested that after the birth maybe the baby could have a starring role in 'Enders too!
"I'm sure she'd be up for that", she quipped.
In the meantime, as Jacqueline's baby bump gets bigger, how will producers get around the 21-year-old's growing tum?
Lorna said: "It might be one of those were she has to hold things in front of her belly... like a washing basket!"
Meanwhile, Lorna's on-screen dad Jake Wood (Max Branning) has been busy showing off his fancy footwork on Strictly Come Dancing and the young actress "never knew" her second dad could actually move!
She said: "I thought he was brilliant, he got the highest score on the night! We've seen a few bits of routines coming up - only in rehearsals - he's good, though! Not that I didn't think he would be... when he said it I was like 'oh ok' but now I'm like you can actually move!"
Insisting that Jake won't succumb to the dreaded Strictly curse, Lorna claimed that the actor is nothing like his love rat character Max: "Oh god no! His wife is lovely, they're such a lovely couple," she said.
But even though he's nothing like his alter ego, that doesn't stop women everywhere drooling over Albert Square's resident bad boy.
Revealing she often gets approached by Jake's fans, Lorna joked: "Women come up to me and say your dad's fit... and I hope they're talking about Max!"
