Philly's musical pride and joy Alecia Beth Moore, best known by the masses as "Pink" is pissed at a handful of her fans.

The singer posted a heated open letter Saturday in response to a slew of "hate mail" she says she's received after canceling her April 22 show in Birmingham, England due to a chest and ear infection.

"I had absolutely no choice in the matter, no control over the circumstances, and physically could not get my sick a-- on stage," she said. "Even a doctor told me I could not go on stage whether I wanted to or not," she continued.

She then apologized "AGAIN" for any inconveniences caused to fans who anticipated seeing her in show. "I actually rode by the venue, and saw some of you in line," wrote Moore who added, "My heart was absolutely broken."

"That's why I never phone it in," she continued. "I go on stage and pour my f---ing heart and body out on that stage. I ruin my body and my vocal chords, make myself sicker, come hell or high water. I don't lip sync, I don't rely on dancers to do my work for me. I try to put the best show on that I can, that any human being can, and I don't stop until I know you're happy."

Pink beseeches her fans to give her the "benefit of the doubt" rather than turn into "rabid dogs" that "question the moral fabric" of her character.
