Pink, Willow and Carey Hart hit up the beach in Miami on Monday, building sandcastles, chasing waves and showing off their ultra-fit, tattooed frames.

The singer, who gave birth to daughter Willow just 14-months-ago, wore blue bikini bottoms and an itsy-bitsy top.

Speaking of losing 55 pounds and reshaping her post-baby body, Pink shared previously:

“I love to feel fit. I love to feel healthy. I wasn’t in a race. I was really kind to myself because I was actually really impressed with the fact that I had just had a baby, like ‘I made a human!’”
