BOSTON, Mass. -- Caption Cameron Diaz poses with Choice Summer Movie award for ‘My Sister’s Keeper’ in press room during the 2009 Teen Choice Awards held at Gibson Amphitheatre in Universal City, California on August 9, 2009 Cameron Diaz has surprised Boston Celtics players and about 125 volunteers by participating in a charity project on the anniversary of the Sept. 11, 2001, terrorist attacks.

The “Charlie’s Angels” actress worked for two hours Friday with Celtics guard J.R. Giddens and forward Bill Walker, elementary school students and volunteers to build flower beds around a Boston elementary school.

Volunteers also created a basketball court, an outdoor classroom and a garden at the Young Achievers Science and Mathematics Pilot School in the Mattapan neighborhood.

Diaz was in Boston ahead of filming “The Untitled Wichita Project” with Tom Cruise next week in the central Massachusetts city of Worcester.
