The battle of the bimbos: Kim Kardashian vs Paris Hilton

IS it time Paris Hilton gave up the day job, whatever that might be?

The blonde heiress - who is famous just for being famous - tottered into the spotlight at the tender age of 16.
But now the 30-year-old is facing competition from an abundance of other rich, pretty reality TV stars. And she isn't happy about it.
Paris stormed off a US TV show this week after being asked if she was a has-been who has been overshadowed by rival socialite Kim Kardashian, 30.
Both rake in millions a year but neither have any real talent or a proper job.
So is Paris, the girl who patented the phrase "That's hot", no longer that hot?
