Rosie embraced her pregnancy, posting snapshots of her stunning baby shower a month ago on social media.

She also shared photos from her 30th birthday celebrations back in April, gushing that she felt 'life is just about to begin' during her enthralling year.

'Thank you to everyone for all the special birthday wishes!My heart feels full of warmth and love turning 30 today!'She wrote a letter from the ruins of her grandmother.

'Being that it's such a big milestone, I can't help but reflect and reflect on all that life has given me, while still looking forward to the future and feeling as if life is about to begin... quite literally.'

'Bye Bye 20's you were hot, hello 30's can't wait to see what you got in store for me!!'JustGettingStarted #1987 #JustGettingStarted #1987.'

In January last year, Rosie confirmed her relationship with Denis.

In a rare interview with Harper's Bazaar Australia, Rosie praised Denis saying: "I have an amazing friendship with my partner." "He has by far the most influence in my life."

The actress, who was obviously excited for motherhood, said in an interview with Karen Salazar back in 2012 that caring for her child would be her first priority as the time comes.

"I always imagine myself working, but being a mother will be a big part of me," she said. I believe there is a point where you say, 'I don't worry about myself as the number one any more.' 'I want to worry about other things.'

However, she has also stated that living away from her family in Salazar would be difficult, and that raising a family will make it more difficult, and that the couple will need to consider carefully how they decide on a home if they move forward.

I'd like having a family and asking whether I'd live here in the United States or in England is something I'm considering.' But it isn't always as simple as that. I have no idea what will happen, but it'll be interesting to find out, right?And there will be no such thing as flawless, I'm sure.

"Not being in Los Angeles] is the one big drawback [of being in Los Angeles]. I would love to be able to invite them over for a roast dinner, or be able to say to my brother or sister, 'Why don't you pop over for a glass of wine tonight?'I can't, but it does weigh on me.'
