Kristin Cavallari has her post-baby bikini body back and is looking hotter than ever.
The 26-year-old mom, who gave birth to son Camden last August, showed off her slim physique while taking a dip in the pool during a recent trip to Mexico.
Cavallari's tummy looked oh so toned in her colorful and tiny two-piece bikini as she waded in the water.
Cavallari is south of the border for a girl's trip sans fiancé Jay Cutler. One of her pals tweeted a of photo of them having fun in the sun by the beach the other day.
