Now that her plan to divorce Arnold Schwarzenegger has become public, Maria Shriver walked alone along the beach in Malibu.

Shriver, wearing no makeup and looking sad, chatted non-stop on her cell phone.

Arnold's soon-to-be ex was reportedly offered an excess of $15 million for a tell-all book about her life, however various online reports claim she has turned all the offers down. Ms. Shriver was also offered several TV deals from major networks, but she has reportedly refused those offers, as well.

Arnold and Maria's daughters Katherine and Christina spent time together shopping at Planet Blue in Malibu. See them shopping in the gallery below. Check out mom Maria enjoying some retail therapy at the Malibu Country Mart ... after the jump.
