She is the reality television star who has everything - well almost everything. And now Kim Kardashian has shown she is happy to share.

Kim, 31, took delivery of a Lamborghini at her Los Angeles home yesterday and soon afterwards took it out  for a spin.

The reality TV star splashed out on the luxury motor for her boyfriend Kanye West’s 35th birthday today, according to TMZ.

Even though the rapper is currently in Ireland on his Watch The Throne world tour, his caring girlfriend got the car delivered before she flew out to visit him today.

She then made a video of the present and will screen it for him after his show in Dublin tonight.

The 2012 Lamborghini Aventador doesn't leave much change from $400,000. The Aventador LP700-4 can do 0-60 in 2.9 seconds and has a top speed of 350 km/h.

The car company named the cat 'Aventador' after a bull that entered into battle on October 1993 at the Saragossa Arena, earning the 'Trofeo de la Peña La Madroñera' for its outstanding courage.
