So I attended a fab party the other night at Kiehl’s on Montana Avenue in Santa Monica in honor of Earth Day.  The staple skincare brand teamed up with Michael C. Hall (“Dexter”) and Chloe Sevigny (“Big Love”) to create a limited editon collection of Kiehl’sRare Earth Deep Pore Cleansing Masque with 100% of net proceeds benefitting Waterkeeper Alliance, a charity founded by Robert F. Kennedy Jr., that supports local Waterkeeper programs to provide a voice for waterways and their communities worldwide.

There were plenty of other celebs in attendance as well- we spotted Stephanie Pratt (“The Hills”) at the restaurant next door and then at the party, Kristin Cavallari (also of “The Hills”) who embraced Stephanie with a hug as soon as she walked in.  Mario Lopez was there with his wife, as well as Sam Trammell from “True Blood,” who is even cuter in person.
