So much star power in one photo!

Reese Witherspoon, Charlize Theron and Salma Hayek attended Sean Penn's Help Haiti Home Gala at the Montage Hotel in Beverly Hills on Saturday, and the ladies looked amazing when they struck a pose together. Witherspoon was joined by hubby Jim Toth, and Theron took some time to pose with Penn, to whom she got engaged last year.

Penn started the J/P Haitian Relief Organization in 2010 following the country's devastating earthquake, and last year's event raised $6 million. The J/P HRO's mission is to "save lives and build sustainable programs with the Haitian people quickly and effectively," and they've worked hard to relocate some of the 60,000 people who were residing in the Petionville and Cite Maxo displacement camps.

Other stars at the event included Chris Martin, who performed, along with Ben Stiller, Rachel Zoe, Eric Dane, Rebecca Gayheart, Garcelle Beauvais, and Pamela Anderson.
