It will have been a welcome break for the family, who endured COVID-19 lockdown at their family home in Los Angeles.
Sistine and Sophia have also recently been reminiscing about the 'beautiful life' of their grandmother Jackie, who passed away last month at the age of 98.
During an episode of Heather Dubrow’s World on PodcastOne last week, the duo revealed that their grandma was still tap dancing and doing Pilates before her death.
'What did you get from your grandma?' the podcast host asked.

'You know, it's so funny, when I was younger, every time I went over to her house, she had these little Beanie Babies, she collected,' Sistine recalled, before revealing she has about 50 of them in her room.
On a more reflective note, Sophia said her grandmother taught her she didn't have to have her entire life mapped out just yet.
'You have your whole life to be old,' Sistine quipped, of what her grandmother would always remind them.
The models' uncle, Frank Stallone, announced the news of Jackie's death with a Facebook post last Monday, revealing she 'died in her sleep as she had wished.'
The 70-year-old Grammy Award winner also wrote that Jackie 'was a remarkable woman' who worked out 'everyday' and was 'full of spunk and fearless.'
'It was hard not to like her, she was very eccentric and flamboyant person.'
Frank provided some impressive details regarding his mother's life, including that she 'lived through prohibition, the depression and World War II.'
