Jessica Alba has become synonymous with flawless beauty ever since she hit our TV screens back in 2000 as the lead actress in "Dark Angel." While she was only 19 years old at the time, it seems as though she's barely aged in the 15 years since. Check out our photo gallery of the best photos of Jessica Alba, featuring her sexiest looks from 2014 and 2015!

From a bikini on the beach to a dress on the red carpet, Alba has no problem radiating beauty.

The 33-year-old mother-of-two still tops annual lists as one of the sexiest women in Hollywood - or rather, the entire world. And it's no doubt why from the photo gallery above!

The effortlessly gorgeous star, who still rocks a perfectly toned bikini-body even after having two children, was most recently spotted in St. Barths looking very model-esque.

The actress strutted around the beach in a tiny string bikini as she snorkeled and played with her daughters and husband.
