JESSICA ALBA has been taking some well-earned time off and has been snapped sunning herself up on board a glam yacht in Hawaii.

The looked absolutely flawless as she donned a black sports bikini and spent the day at sea enjoying diving and surfing.

She has more than earned her time off after letting her acting career take a back seat as she created product empire The Honest Company - which is now estimated to be worth around $1billion.

Jessica looked like she didn't have a care in the world as she donned diving gear and went for a splash in the crystal blue waters just east of Maui.
