Guests at a party in Las Vegas would have needed a knife to cut through the tension between Paris Hilton and Kim Kardashian.

According to HollywoodLife.com, former BFF's Paris and Kim, completely ignored each other when they were sat at the same table at the event.A source who noticed the chilly atmosphere, said:

“Paris arrived at around 3am and was on the same table as Kim but they remained frosty and didn't look at each other or even speak.”It is thought that the reason why Paris and Kim won't utter a word to each other, is because hotel heiress Paris is jealous of Kim's increasing fame.C'mon girls, surely there must be enough spotlight for two people in Hollywood!

In my opinion, Paris Hilton is only famous for her daddy & his hotels. She should be like her sister & just sit back & spend daddy's money. Kim, on the other hand who wouldn't love her she is out here grinding. She is making her own money. So my advice for Kim Kardashian is keep doing you to hell with Paris. I'm pretty sure Kim Kardashian is not worried about Paris Hilton.
