Jessica Alba attended the launch of her new collaborative jewelry line at the Sunset Tower hotel last night, and she looked gorgeous when she struck a pose with preggers pal Molly Sims.

Alba teamed up with bestie/jewellery designer Jennifer Meyer to create necklaces that benefit the (RED) charity organization, and the bash was hosted by (RED) and Gilt. Kerry Washington, Rachel Zoe and Ellen Pompeo were also at the event, as were some of Alba's less famous BFFs.

The necklaces come in 8 carat gold or 18 carat gold with rubies, and the proceeds from the sales will go towards the fund that provides essential medication to pregnant HIV-positive women in Africa. Jess told WWD, "We realized that hearts were a perfect metaphor for this project…it's an easy, elegant design that women can keep close to their hearts ... It makes so much sense for us to collaborate on what we love, use the power of our platforms, and amplify what we do to help eradicate one of the worst diseases. Helping women and children has always been a priority for me."
