She gave birth to her second child less than a year ago, but looking at Jessica Alba's body, you would never know she had been pregnant twice.

The 31-year-old actress showed off her fantastic figure today while holidaying in Italy.

Jessica was feeling the heat and decided to spend most of her time in the swimming pool wearing a two-piece, highlighting her slender frame.

Joined by some female friends, her mother and her two daughters, Honor, four, and eleven-month-old Haven, the Fantastic Four star displayed a flat stomach and a sun kissed skin tone.

Jessica's swimwear consisted of a red and white printed halterneck top and drawstring bottoms.

The actress wasn't bothered about her long dark hair getting wet and decided to leave it down as she played with her children in the water.

She completed her look with a pair of dark sunglasses and appeared happy and relaxed while enjoying some quality time with her family.

Jessica made sure that both of her daughters were well-protected in the sun with Honor wearing a long-sleeved blue patterned swim top and pink bikni bottoms.
