The delightful snap was shared by Sally, 42, who catalogued the family’s fun-packed break to the Bahamas.
The proud mum and wife even posted a video on social media of Ronnie, 72, teaching three-year-olds Gracie and Alice how to hula-hoop, below, at their beach-front villa.
She captioned the clip: “Holiday hula-hooping #seriousbusiness,” before uploading more photographs to Instagram.
Several were taken during an trip to a chocolate factory – where they all tried their hand at making sweets.
Another picture shows a shirtless Ronnie running out of the sea with a bucket of water, probably to soak his wife and kids.
After the sunshine break, the family travelled to the US for more high jinks.
The final picture is of Gracie and Alice wearing their water wings and waving an American flag at a lido.
Sally and Ronnie, who live in south-west London, have been documenting their daughters’ lives since they arrived in 2016.
The Start Me Up guitarist – married to Sally for seven years – recently admitted: “Any time I’m with her and the girls, that’s the best for me, nothing tops it.
“When the twins come into our bed and we’re all snuggled up together, that, for me, is wonderful – my idea of heaven.
“It’s special. The girls are so cuddly and gorgeous. I’m a lucky man.”
He also has three sons – Jamie, 45, Tyrone, 36, and Jesse, 43 – and daughter Leah, 41, from his previous two marriages.
