Rock singer Pink showed off her toned figure and rock hard abs in a bikini on a Miami beach on Monday.

The Blow Me (One Last Kiss) singer wore a striped bikini top with pink cutoff shorts and sunglasses during her family outing with her husband, BMX race car driver Carey Hart, and their daughter Willow, 20 months.

Pink also tweeted about their Disneyland trip on Monday.

"Willz hit me in my temple w a light saber so hard I saw stars," Pink wrote on Twitter. "Then kicked me in my face+gave me a fat lip.I'm never giving her icecream again"

The singer later tweeted about the compliments she has received for her svelte figure.

"all the comments on my "body" good +bad,this body is capable of so much. Im grateful for my strong body that carries me thru the world," she tweeted.

Pink has also been showing off her six-pack and super fit physique on her latest Truth About Love. The singer performs acrobatics during her concerts.

Pink appeared on the cover of the November 2012 issue of SHAPE magazine where she revealed her 55 pound weight loss.

Pink admitted she refused to "rush" into losing the baby weight. But when she was ready, she initiated the help of celebrity trainers Jillian Michael of "Biggest Loser" and Jeanette Jenkins.

"They both kicked my butt more than any other person I've worked out with," said Pink. "They're both amazing, and their bodies were all the inspiration I needed to get back into shape." She committed to work outs six days per week, consisting of cardio, strength training, power yoga and kickboxing. Yowza!"

In addition to working out really hard, the self-admitting former wild child shared that while she maintains a primarily vegetarian diet, she will occasionally eat lean fish or chicken.

Pink and Hart met in 2001 and married in 2006. After a rocky off-and-on relationship which was documented in her song and video So What, the couple gave birth to their daughter, Willow Sage Hart in June, 2011.
