Oops! Katy Perry shares phone number with millions of followers by mistake

Katy Perry accidentally gave out her phone number to her million fans after she shared a video of her dog.

The California Gurls singer uploaded a video of her dog Butters to her Instagram and Twitter accounts - but failed to notice that her phone number was on full display on the dog’s collar.

She captioned the video, “B**** BETTER HAVE MY MONEY IF B**** WANTS SAUSAGES!” – a reference to Rihanna’s new single B**** Better Have My Money.

Perry, 30 - who treated fans to a picture of her new Kris Jenner inspired hair on Wednesday - has since deleted the video and deactivated the numbers.

Some concerned fans quickly informed the star that she had posted her phone number with one tweeting: "idk if it's your phone number but you should kinda see this..."

Others were sad that they had missed out on the chance to call Perry with one user tweeting: "hi there would you just re connect your number so we can send you a video of us singing walking on air thank you."
