The actress couldn’t resist joining the fun on the slippery dip and swings at a park in Sydney.
Back home in Oz to film the live action/animation Peter Rabbit, Rose was joined by her rumoured fiance, US actor Bobby Cannavale.

February 1st marks Rocco’s first birthday! And to celebrate the milestone, Bobby shared this gorgeous snap and penned: “Happy Birthday my beautiful boy #therock #1.”
The actress worked a casual look with a stylish sunhat and chambray shirt.
You’re never too old to have a ride down the slippery dip!
Right, Bobby?
Rocco, who has just turned one, is the spitting image of his actor father.
Look at me walk, mum and dad.
Rose is enjoying her new film role in Peter Rabbit.
“It’s one for Rocco,” she says of the upcoming movie.
Bobby and Rose have been together since 2012.
Speaking of becoming a mother, the Aussie actress says it’s been one of her biggest joys.
“You have this huge responsibility you didn’t have before – there’s someone you have to keep alive. I also like to think Rocco has brought out better qualities in me,” she told Sunday Style.
