Jessica Alba showed off her sizzling bikini body while indulging a boating trip during her family vacation to Italy on Saturday.

The 41-year-old has been traveling with her silver fox husband Cash Warren and their children Honor, 14, Haven, 10, and Hayes, four.

Jessica showcased her taut midriff and bared a bit of cleavage in her fashionable black swimsuit, which she complemented with a pair of matching shades.

Sweeping her hair tightly back up into a bun, she could be seen enjoying a conversation with her daughters as they all basked in the sun.

Meanwhile her heartthrob husband could be seen lounging shirtless across the front of the boat and gazing out across the waves.

In contrast to some of the ancient seaside towns in Italy, Sabaudia dates back only to the Fascist era and was built on former marshland that was drained under Mussolini.

However Jessica and her family did get to immerse themselves in Italian antiquity, as they were also spotted earlier strolling around Rome.

Jessica cut a stylish figure in a Mediterranean chic ensemble that included a blue-and-white floral skirt and a Dior visor.

She flashed the flesh by leaving her white blouse mostly open over her matching bralette and tying it at the waist.

Cash, who is the son of Hill Street Blues actor Michael Warren, met Jessica while assistant directing her critically savaged 2005 hit film Fantastic Four.

The couple spontaneously decided to get married at a Beverly Hills courthouse one day in 2008 while Jessica was heavily pregnant with Honor.

Although she rose to fame as an actress, Jessica is also the founder of the consumer goods brand The Honest Company, which she launched in 2011.

During a 2018 interview with InStyle she shared that ‘I feel like my purpose in life was to create Honest, and everything led me to that.’

Jessica took the Honest Company public over a year ago and it was valued at almost $2 billion on its first day of trading.
