Jessica Alba has been spending the past year in a business attire as she expands her impressive $1b empire The Honest Company, which makes everything from lotion to apple juice.

But on Friday it was all about taking the power suit off as the 35-year-old actress stripped down to a fuchsia string bikini to take a dip in the ocean.

The Fantastic Four star was on vacation in Lahaina, Hawaii - which is on the west coast of Maui - with her husband Cash Warren and their two children Honor, aged eight, and Haven, aged four.

The California native seemed to be uncomfortable with her teeny bikini, however, as she pulled at it here and there as she waded in the water then got out to towel off.
