Jessica Alba Hot Shots to Celebrate Her 44th Bday!

Jessica Alba just keeps getting better with age.

The actress is celebrating her 44th birthday today and we're celebrating by looking back at some of her sexiest looks over the years.

There's some throwbacks ... but Jessica's still looking fine as ever in some of her more recent thirst traps.

Jessica's greatest hits check all of the boxes -- bikini pics, workout shots, poolside photos, gym selfies, mirror selfies, yoga pants, lots of beach vacations ... you name it. Jessica's got it.

Jessica's going through a divorce now with estranged husband Cash Warren ... and she's giving a masterclass in post-breakup hotness.

Happy Birthday Jessica!!!
