Rose Byrne, 41, shows off her toned figure in a black bikini in Byron Bay

She’s enjoying being back in her native Australia while her partner, Bobby Cannavale, films upcoming Hulu miniseries Nine Perfect Stranger.

And Rose Byrne, 41, couldn’t wipe the smile off her face while enjoying a day at Wategos Beach in Byron Bay with her 50-year-old beau on Tuesday.

The actress and mother of two beamed as she went for a dip in the ocean, before returning to the shore for some hijinks with Bobby.

The couple enjoyed some quality time without their children, sons Rocco, four, and Rafa, three, as they soaked up the sun.

Rose, who hails from Sydney, showcased her impressively toned figure in a black bikini, while Bobby looked buff in a pair of green boardshorts.

The pair, who refer to each other as husband and wife but aren’t legally married, went for a refreshing swim then dried off on the beach.

At one stage, the Boardwalk Empire star jumped into the air to amuse his partner-of-eight-years, and she certainly looked impressed by his efforts.

They then relaxed on their beach towels and spent time chatting, before packing up their belongings and heading home. 

The couple and their children are living in Byron Bay as Bobby films TV series Nine Perfect Strangers, which is being produced by Nicole Kidman.

Little has been divulged about Bobby’s role, except that his character is named Tony and he will be one of the titular strangers.

Last month, Nicole, who is also stars in the show, said she was ‘thrilled’ to be able to bring hundreds of jobs to the local film industry, after it was sent crashing down by the coronavirus pandemic.

‘It is a great opportunity for me to give back to the community that nurtured me through so much of my career,’ she said.

Nine Perfect Strangers is based on the 2018 novel of the same name by author Liane Moriarty, who also wrote Big Little Lies.

In addition to Bobby and Nicole, the all-star cast includes the likes of Melissa McCarthy, Luke Evans and Manny Jacinto.
