Robert Pattinson loads up on groceries with a friend on Tuesday (August 9) in Los Angeles.

Last weekend, the 25-year-old actor picked up two 2011 Teen Choice Awards and shared a new campaign he recently became involved with: Cancer Bites.

“When I heard about the Cancer Bites initiative, I knew very little about how prevalent blood cancer is because there have been so few national campaigns about it,” Robert said.

Rob adds, “The Cancer Bites campaign officially launches on October 31, but in the meantime you can go to www.cancerbites.tv for more information about how you can spread the word to support those who are dealing with this type of cancer.”
