Wave your arms in the air like you just don’t care - because Paris Hilton did - and proved that even the richest of celebrities have to fight the fuzz!

With all her glamorous partying over the weekend, it appears that Paris chose to reach for her lip gloss over her razor!

But the sweat must have been worth it, as the Hilton sisters couldn’t get enough of Las Vegas as they celebrated Nicky’s 25th birthday.

On Saturday they danced the night away at LAX and last night they continued their boogie on the VIP stage at Pure nightclub.
