Cameron Diaz has gone blond, brunette, short, and long, but never bald ... until now. The actress donned a bald cap for her role in "My Sister's Keeper," about a girl battling leukemia and the strife it causes within her family. Diaz plays a mom who shaves her head in support of her ill daughter, played by Sofia Vassilieva. Oscar-nominated actress Abigail Breslin co-stars in the movie, due out in 2009.
