Kanye West is reportedly planning to spend $1 million on Kim Kardashian's birthday next month.

The pair started dating earlier this year after Kim's high-profile split from husband Kris Humphries.

Kanye and Kim are said to be smitten with each other - so much so that Kanye is preparing to spoil his girlfriend on her upcoming birthday.

"Kim has been really down about turning 32 and having two failed marriages behind her and no children, so he wants to make this extra-special. Plus it's her first birthday since they've been together as a couple," a source told British newspaper The Sun.

"Kanye has never been shy about splashing out on the women he loves, but this time he's pulling out all the stops with presents."

According to the publication, Kanye has organised a trip with a group of friends on a private island in the Turks and Caicos.

He's reportedly organised a chef from a five-star hotel to "cook for them privately every night" while they are there.

The rapper-turned-designer has also been splashing out on designer items for his gorgeous girl, whose birthday is October 21.
