Pink is standing up against critics of her weight.

The 35-year-old pop star was photographed Saturday night at the John Wayne 30th annual Odyssey Ball in Beverly Hills, California, and apparently heard some negatives comments about the way she looked.

She posted a message on Twitter, admitting that her dress "didn't photograph as well as it did in my kitchen."

"I can see that some of you are concerned about me from your comments about my weight," she tweeted on Sunday. "You're referring to the pictures of me from last night's (Saturday) cancer benefit that I attended to support my dead friend Dr. Maggie DiNome. She was given the Duke Award for her tireless efforts and stellar contributions to the eradication of cancer. But unfortunately, my weight seems much more important to some of you."

She went on to note, "In fact, I feel beautiful," before telling fans not to worry about her.

Pink also tweeted that her husband, Carey Hart, and their daughter, Willow, are just fine with the way she looks:
