The 'Keeping Up With The Kardashians' star shared a new picture on the image sharing site in order to mark the milestone and wrote a message of thanks to her fans.

She captioned the picture: "55 MILLION!!!!!!!OMGGGGG!!!!!! LOVE YOU SO MUCH!!!!!!! (sic)."

Kim reached 55 million followers just one day after her mother Kris Jenner got her number up to 10 million.

Alongside a collage on her page, she wrote: "Thank you so much for following me ... Can't believe it's 10 MILLION of you!!!! You are amazing!!! I am appreciative and grateful and feeling humbled and blessed...

"Merry Christmas everyone, don't forget to tell those you love how special they are.... God Bless You!!! (sic)"

Meanwhile, Kim and her husband Kanye West recently welcomed their second child.

The reality TV star gave birth to the couple's son Saint earlier this month and it has been claimed that they will hold his baptism in Jerusalem next year.

They did the same thing with their daughter North, two, in April and are apparently keen to have a similar religious ceremony for their little boy.
