In 2011, she traveled to Japan with her "90210" costars AnnaLynne McCord and Jessica Stroup to attend the Asia Girls Explosion (AGE) in Tokyo, after filming "90210" third-season finale. Grimes was caught up in Japan due to the events of the tsunami and earthquake. According to the actress, she was at Buddha's temple at the time when the earthquakes first occurred. Consequently, she started a campaign called "Spread The Heart" with the aim of supporting Japan by victim relief after the events of the tsunami and earthquakes. Many celebrities joined the campaign which later became a big movement.
