She's currently giving ex-husband Ethan Hawke some moral support while he promotes his latest film at the 71st annual Venice Film Festival, but Uma Thurman swapped the spotlight for a day with the family on Friday.
The 44-year-old actress was joined by children Maya, Levon and Rosaline for a picturesque boat ride through the ancient city's famous waterways.
Sporting a casual white top, skinny jeans and sandals, Uma was in high spirits as she boarded the small boat with infant Rosaline, nicknamed Luna – her daughter with former fiancé Arpad Busson – strapped into a body harness.

Appropriately named DIVA, the modest taxi-boat speeded Uma and her three children across the canal while they chatted amongst themselves in the rear.
The Kill Bill actress had previously treated the family to ice-lollies as they took a quiet stroll away from the thong surrounding this year's film festival.
Ex-husband Ethan's new move, Good Kill, is up for the festival's main prize, the Gold Lion, alongside 54 other new projects, including Al Pacino's Manglehorn and Birdman or the Unexpected Virtue of Ignorance, led by Michael Keaton.

Uma has been focusing on bringing up little Luna following her split from her father, businessman Arpad Busson, before Easter earlier this year.
It was the second time the pair had called off their engagement - the first time came in 2007, two years after they began dating.
The break-up came when Luna was around 21 months, and Uma has admitted that she is stunned by how fast their little girl has grown up.

She said: 'I mean, especially having a child later… you barely have a chance to touch them before they're spinning off in the universe.'
Meanwhile, the stunning actress has recently opened up about another hugely important man in her life - Pulp Fiction director Quentin Tarantino.
In the new issue of Vs. Magazine, she revealed: 'I was discussing [the rumors] with Mr. Tarantino last night.
'He was angry at me for not calling him back because, as he said: "According to the papers we are practically married!" and he laughed hysterically.
'So our relationship is pretty much what it's always been; people are just having fun with it.'
