'I feel beautiful,' says Pink, shutting down critics 'concerned' about her weight

Pink has posted an open letter for so-called fans who seemed "concerned" about the singer's weight after she appeared at a cancer benefit this weekend in Beverly Hills.

The 35-year-old American pop star, whose 2006 song Stupid Girls poked fun at celebrity beauties, received less than flattering comments after she was photographed Saturday in a black cocktail dress at the John Wayne 30th Annual Odyssey Ball.

But the mother of one refused to take the fat shaming comments in silence, telling critics "While I admit that that dress didn't photograph as well as it did in my kitchen, I will also admit that I felt very pretty. In fact, I feel beautiful."

"I'm perfectly fine, perfectly happy and my healthy, voluptuous and crazy strong body is having some much deserved time off," Pink tweeted Sunday.

"Thanks for your concern," she wrote, signing the note "Love, cheesecake."

Fans embrace her message

Pink's self-love missive inspired an outpouring of support from her fans, who shared pictures of their bodies with the pop star.

The singer, who is married to professional motocross racer Carey Hart, took time to respond to their messages, re-posting some of them to her 26 million followers.

She also shared a photo of herself in the black dress, posing with her daughter Willow, adding the caption:

"Willow said to me the other day whilst grabbing my belly-"mama-why r u so squishy?"And I said.."b/cuz I'm happy baby"
