“Happy birthday @Pink,” the person wrote alongside an image of Eddie on a red carpet, appearing to mock Pink’s appearance.

The message was met with a swift response from the ‘What About Us’ singer, who shared that she had shown the tweet to her 12-year-old daughter.

“I explained to her that I’ve never met you, I don’t know you, and I have no idea why you would go out of your way to be hateful,” she continued.

“It was a good lesson in ignorance.

“Thank you. I still don’t know you. Congrats.

“You’re no one.”

In a separate tweet, Pink shared that she believes “most people are smart, good, and rad” and that online trolls are “anonymous, lonely, and miserable”.

She went on to share the original tweet once again, referring to it as a “wasted opportunity”: “There are so many pictures you could’ve chosen that were actually me that were worse than this picture, you nameless f***o. At least be creative next time dum dum.”

“I post these things to show the kids I know- my own kids as well, that we are all occasionally treated badly,” Pink went on to tell fans.

“I show them because they know me, and they know that my self-esteem does not rely on the opinions of others.

“Nor does it rely on how many tickets I sell. Good/bad. Whatever. I love me. Now I shall sleep really really well.”

Pink, who turned 44 last week, is one of the world’s best-selling music artists with global sales of more than 135 million records.

Her latest album, Trustfall, was met with a positive response from both fans and critics and reached number one and two in the UK and US, respectively.
