In her latest photo on Instagram, pop star Jessica Simpson has shared a snap of her two adorable kids, Maxwell and Ace, playing by the pool and showing how the Simpson-Johnson family likes to be in their bathing suits!

Because the two were only born 14 months apart, they actually look more like twins!

Simpson captioned the photo, "14 months apart and my blondies are trying to figure out which one will share or get thrown in."

In the photo, Maxwell, 4, and Ace, 2, are sitting on the edge of the Los Angeles pool trying to beat the heat — each with a toy fish in their mouth!

Maxwell wears a cute white two-piece bathing suit, while Ace is decked out in pink and purple shorts with printed turtles on them.

The photo comes just a few days after Simpson shared another cute photo of her kids for her husband, former professional football player Eric Johnson, for Father's Day!
