Kellan Lutz just Tweeted the above pictures and said, “Great day having cast mates Rami, Casey, and Richard come and get dirty with me, working on Rosalie’s house with the St. Bernard Project. ”

Kellan has done charity work with this group before with former girlfriend Anna Lynn McCord. According to the group’s website this is what they are all about:

“Mission
The mission of the St. Bernard Project is to create housing opportunities so that Hurricane Katrina survivors can return to their homes and communities. The St. Bernard Project, a nonprofit, community-based organization carries out its mission through three primary programs: Rebuilding Program, Center for Wellness and Mental Health and Opportunity Housing Program.

History
The St. Bernard Project was started in March 2006 by Zack Rosenburg and Liz McCartney after the couple volunteered in St. Bernard in February. During their initial month of service, they met residents who were courageous, spirited and determined to rebuild their lives and community. They shared their stories, opened their homes and made Liz and Zack laugh, cry and question their own values. Inspired by the residents’ collective spirit, openness and fierce desire to rebuild their lives and community, Zack and Liz decided to create an organization that would provide vital resources and support to families in a seamless and timely manner. The St. Bernard Project’s programs and goals are directly driven by the needs expressed by the community members.”

We are assuming that Rosalie is the lady in the photo with the Tweetie Bird shirt. As for who the heck Richard is, we have no idea, but he sure is tall. Maybe, Dan Cudmore’s stand in?(EDITED: Consensus on Twitter seems to be that Richard is Kellan’s personal assistant.)
