Singer Katy Perry accidentally gave out her phone number to her millions of fans after sharing a video of her dog Butters online.

The singer shared the number by chance on micro-blogging platform Twitter and image-sharing website Instagram on Wednesday, reports usmagazine.com.

The `Wide Awake` singer, who also shocked her fans by cutting her hair into a 'Kris Jenner' pixie hairstyle, posted a video of her beloved dog Butters without realising that his dog tag perfectly displayed her phone number.

`B*TCH BETTER HAVE MY MONEY IF B*TCH WANTS SAUSAGES! (Sic)` she captioned an image of her pooch, giving singer Rihanna's new jam "B*tch Better Have My Money` a shoutout.

Soon after she shared the photograph on both Twitter and Instagram, a majority of her fans tried to call her.

After receiving likely millions of calls, Perry quickly deleted the video and photograph, and then deactivated the numbers.
