The reality television star has finally shared the first photos of her newborn, Penelope Scotland.

Kourtney Kardashian chose Us Weekly magazine to delight fans and introduce her little girl to the world.

Kourtney is also mother to two-year-old Mason with her boyfriend, Scott Disick, who also takes part in the 'Keeping Up With The Kardashians' show.

In the cover interview the reality star said she was entirely unprepared for the amount of love she feels for her newborn daughter.

Kourtney speaks to Us Weekly about her new baby, Penelope.

She said: “Nothing could prepare me for how hard I fell in love with her!”

Kourtney did the photoshoot with just herself and the two kids.

The reality television star gave birth to her daughter Penelope Scotland in LA on July 8^th, weighing 7lbs 14oz.

Kourtney shares a picture of a book she's reading on Twitter, brushing up on a bit of parenthood.

In true Kardashian form, her siblings took to the micro-blogging site Twitter to congratulate herself and Scott on the birth.

Kourtney's sister Khloe wrote a whole blog about how perfect Penelope was when she was born.

“The entire family is exploding with joy and have not stopped fawning over our new little girl,” she wrote.

“And Mason is already loving being a big brother! This is just such a special and happy time for my family. Thank you to Kourt and Scott for making such beautiful babies! LOL”

Kourtney, however, remained silent on Twitter about the new arrival, apart from sharing a picture of her new necklace, a two-disc design featuring the letters M and P for Mason and Penelope.
