The couple tied the knot in 2015 and the brunette beauty has been documenting their vacation in Positano to mark their fifth year of dating.

Alongside a snap of the pair chilling on a sofa, she wrote: "Summer vacation #our5thaniversary (sic)"

The 'Hot Pursuit' star also shared pictures of their evening date, and wrote: "Happy nights."

Meanwhile, on July 4th (Independence Day) Sofia and Joe took a sun-soaked boat trip to the Gulf of Salerno.

Alongside a picture of the pair each posing on the back of the boat, she wrote: "Going to lunch."

The 46-year-old Colombian-American actress concluded her holiday roundup with a picture of her in a stunning figure-hugging white dress whilst the 'Magic Mike' star wore a casual black shirt and striped trousers, with the stunning Italian scenery in the background.

Sofia gushed: "My favorite place with my favorite (sic)", and added four heart emojis.

Meanwhile, Sofia previously gushed that she is attracted to the 42-year-old hunk even more because he's a "nerd" and doesn't realise he is handsome.

She said: "I mean, he's so good-looking, he's so handsome, but that's nothing that's ever in his vocabulary or he doesn't even know about it.

"To be with somebody that is like that and also very intellectual and intelligent -- because he's like a nerd -- is kind of, it's hard to find, so I love that about him."

Whilst Joe loves his wife's entrepreneurial spirit.

Sofia - who has 26-year-old son Manolo with first husband Joe Gonzalez - said her attitude towards "work and business" has only served to make Joe fall for her more.

She said: "He loves that I love to work, that I love to be creative, that I'm always planning my ventures, that I'm always excited about work and about business. He loves that."
