The tropical jaunt was a hard-earned respite for the Honest Company founder

LONDON: She's known for her killer body. But Jessica Alba certainly wasn't protecting her assets as she hit the beach in St. Barts on Sunday, reported the Daily Mail.

The actress sported the beginnings of a painful sunburn

while showing off her toned figure during a casual stroll along the coastline with husband Cash Warren.

The pair, married since 2008, looked ever the perfect couple in stylish swimwear.

Alba, 31, wore a purple bandeau top complemented by matching lavender-print bottoms that accentuated some major tan lines.

She gathered her ombre tresses in a messy bun atop the crown of her head and topped the look with a set of tortoiseshell sunglasses.

Husband Warren, 34, appeared sporting only a pair of blue-and-white-striped swim shorts for their leisurely stroll on the island, where they've joined pal Nicole Richie on vacation.

The tropical jaunt was a hard-earned respite for the Honest Company founder, whose book The Honest Life joined the New York Times Best Seller List just last week.

In addition, the actress recently wrapped production on two upcoming Robert Rodriguez installments, Machete Kills and Sin City: A Dame to Kill For.

She took advantage of her time on the island, beloved among stars like Gwen Stefani, Beyonce and Rachel Zoe, by stretching her defined arms in the shallow surf.

Later, the actress donned a simple multicolor sundress and a tan fedora to partake in an afternoon cocktail at a resort bar.

Alba and Warren traveled to the seaside hotspot with a group of friends.

The joyful starlet Tweeted on Sunday: 'Love vacay with the homies!' alongside a photo of her lounging with a group of bikini-clad ladies including close pal Nicole Richie.

Noticeably absent from the jet-setting crew was Richie's husband, Joel Madden.

On Saturday the Good Charlotte frontman accepted an Australian TV Week Logie award for Most Popular New Male Talent.

The vocalist currently works as a coach on the Australian edition of The Voice, now in its second season.

The fashionable mums also chose to leave their children at home in Los Angeles.

Alba is mother to daughters Honor Marie, four, and Haven Garner, one, while Richie parents daughter Harlow Winter Kate, five, and son Sparrow James Midnight, three.

Richie relished the Caribbean sun by lounging upon an inflatable raft.

The Fashion Star mentor slipped into a red bikini that showcased her dainty tattoos.

To protect her face from the harsh sunlight, the 31-year-old socialite accessorized her ensemble with a cream belted Panama hat before gracefully testing the crystal-blue waters.
