Did Nicole Richie snub bff Paris Hilton? That's what the New York Daily News is reporting. Nicole ditched Paris Hilton's 26th-birthday bash on Saturday night in Las Vegas. Although Nicole was in Sin City she chose not to attend the bash.

Paris made an announcement on the microphone that Nicole was "on her way", although she never showed up at the Hard Rock Hotel.

The newspaper reports this is a fresh chill in their reconnected friendship, who just recently posed together for a Harpers Bazaar shoot in the Beverly Hills De Beers store just last Tuesday.

Meanwhile Paris is shunning her own friend Kim Kardashian. The heiress didn't invite Kim because she was scared she would steal the spotlight from the red carpet. This is so high school and people really need to grow up and start acting their age.
