The former Miss World, 36, has revealed she is due to give birth to her twin boys, within the next 14 days.
And while her husband Wes will be afforded restricted access to both her and the babies, she says her father Chris is planning an old school tradition of wetting the heads when they finally arrive.
“Wes hasn’t been able to come to scans with me, but he will be there for the birth and will be allowed to visit me in hospital too, so we’re really grateful for that,” she told the
“But it’ll be a busy week for him juggling daddy duties at home with visiting me and helping out with the twins.
“But he’s a fantastic dad and very capable.
“My parents are both unbelievably excited to welcome to two grandchildren and they’re already amazing grandparents to Sophia.
“They spend a lot of time with her and have been a huge support to me during my pregnancy.
“I think my dad plans to celebrate with a little tipple with Wes after the babies are born.”
It has been almost eight months since Rosanna and Wes lifted the nation’s spirits by announcing she was expecting twins.
The couple had baby Sophia last year via surrogate and had all but given up on having children naturally.
And now, as she faces into her first labour, Rosanna says her mother Diane has been a rock of support.
“I’m into the final week or two of my pregnancy, as twins tend to arrive about a month earlier than single babies,” she said.
“I’m grateful to be still feeling well and have escaped any back or pelvic pain, but I am finding it challenging to walk around now with their combined weight of at least 10lbs.
“So I’m trying to put the feet up as much as possible.
“Mom has had three babies herself so she knows what it’s like to have a full, busy home.
“She’s been a great source of advice and has mainly just advised me to rest now at the end of the pregnancy as much as I can.
“She’s also pointed out that Wes and I have plenty of experience with newborns so looking after twins won’t be as daunting as we might imagine it is, as we’ll have plenty of support from family too.”.
Rosanna admitted that the thought of growing from a couple to a family of five in a 12 month period sounds daunting.
But she said that right now she is just looking forward to getting to know the new members of the family, whenever they arrive in time for Christmas.
“Going from just the two of us to a family of five in the space of a single year is definitely quite a change,” she said.
“But we couldn’t be happier that our family is complete and it’s going to be an amazing festive season at home with our babies.
“I’m just really looking forward to seeing their little faces and getting to know these two new humans.
“We do plan to decorate the house before the boys arrive within the next week or two, but we’re still getting the final baby bits and pieces finished so it might have to wait until I’m home from hospital.
Rosanna was speaking at one of her last engagements before the arrival of the twins, where launched the Christmas lights and decorations at Carrickmines Park to mark the start of the festive season.
Living close by, Rosanna is a regular visitor to Carrickmines Park and is a familiar face in all thirty stores to shop for home, fashion, beauty and pet goods. Rosanna was joined today by her dogs, Leo and Ted.
Currently, a number of essential retailers are open at Carrickmines Park and others are operating a Click and Collect service.
“After what’s been such an unusual year for us all, I’m especially excited about this Christmas and of course it will be very special with the arrival of our new twin boys, so we intend to make Christmas as magical as possible for them and Sophia,” she added.
“I’m absolutely delighted to have been asked by Carrickmines Park to officially launch the Christmas shopping season.
“I’m really familiar with Carrickmines Park as I live close by, so I’m frequently there picking up baby, pet, home essentials and gifts for family and friends.
“With so much choice and a huge range of different brands, it’s ideal for getting all of your Christmas shopping done.”
