Kristin Cavallari’s swimsuit body is still enviable after three children.

The Laguna Beach alum looked in amazing shape while shooting the cover of an upcoming issue of Modeliste magazine earlier this month in Puerto Vallarta, Mexico.
For her post-baby body debut the 29-year-old posed in a sexy black bikini.

Kristin, who just gave birth in November to her third child, looked breathtaking in an Agent Provocateur bathing suit.
The bikini-clad cover girl sizzled in the strappy number which showcased her flat abs.
She flaunted her toned and tanned gams by teaming the sultry suit with a pair of gold ankle-strapped peep-toe heels.

The hot mama slicked her long blonde tresses back giving her that wet hair look.
And her make-up was glamorous featuring a deep smokey eye.

Kristin accessorized with a bold Tiger’s Eye gemstone necklace which wrapped around her neck several times and draped into her ample cleavage.
She shared some behind-the-scenes snaps to her Instagram account last week revealing even more alluring looks from the shoot.
