Holly Madison hosted an afternoon pool party this weekend at Tao Beach in Las Vegas. Kim Kardashian was also in Sin City throwing a bachelorette party with Kelly Rowland for their pal La La Vasquez. And there's more…

Pink partied with hubby Carey Hart at his Supercross bash at Wasted Space at the Hard Rock Hotel and Casino's Wasted Space nightclub. Dancing With the Stars' Pussycat Dolls singer Nicole Scherzinger was not far away over at Pure.

And speaking of DWTS, a big birthday celebration for three happened over on the dancefloor the other day with Cold Stone Creamery cakes delivered for Cheryl Burke, Erin Andrews and Tom Bergeron.

Ryan O'Neal and daughter Tatum were among the very crowded party of pretty people checking out photographer Douglas Friedman's new exhibit Take It Off on Friday night at the Jean de Merry showroom on Melrose Place.

Up a bit north from Hollywood this weekend, cooler than cool N.E.R.D. frontman Pharell Williams performed at the Microsoft KIN event at the European Collision Center in San Francisco. Also in the Bay Area was former Desperate Housewives hunk Jesse Metcalfe having fun at Infusion Lounge.

Happy Monday, everybody!
