Rachel Bilson & Kristen Bell: Guess What?

Rachel Bilson grabs her morning coffee and pastry from Coffee Bean & Tea Leaf on Friday (October 23) in Los Angeles.

Last night, the 28-year-old actress and Heroes hottie Kristen Bell attended a t-shirt launch party. GUESS and Vanity Fair unveiled special edition organic men’s T-shirts and women’s tank tops to benefit education and economic rebuilding in the war-ravaged African nation of Uganda. The shirts are now available for purchase at Guess.com. 100% of the proceeds from shirt sales will benefit Invisible Children, a non-profit organization dedicated to supporting youth education and economic development in war-torn regions of Central East Africa.

FYI: Rachel is wearing a Monrow white tissue jersey v-neck t-shirt and James Twiggy jeans in Black Cat on her coffee run.
