Designer Shay Todd with the Nivea Girls

Summer means one thing in Los Angeles. Pool party! Sure, there will be some Haute nightclub openings but all the major parties take place pool-side, with cocktail in hand.

The season kicked off in style with the 2011 NIVEA Good-bye Cellulite, Hello Bikini! Challenge, hosted by Khloe Kardashian Odom.

The big draw was the free Shay Todd limited edition promotional bikini, but guests stayed to lounge by the pool and sipped Acai-based new drink, 28 Black, with mixes well with vodka, or tequila for a margarita. Appropriately, there was bbq, free massages and a fun photo booth (what, you don’t have those at your pool?)

The birthday girl – Khloe who says she is celebrating her 27th birthday all week — was surprised with a cake in one of the cabanas.

Talent included Paris Hilton, Jaime King, Jason Ritter, Rosario Dawson, Lady Victoria Hervey, Ashley Scott, & Susie Abroimet, and Hope Dworaczyk., most sporting their own Shay Todd cover-ups, for the perfect pool party chic.
