The new home is located in the swanky Brentwood neighborhood, not far from the family home she shared with Schwarzenegger during their 25-year-marriage.
Shriver, 55, officially filed for divorce from the former California governor last week - two months after Schwarzenegger, 63, revealed he had fathered a child with a former household employee during his marriage to Shriver.
And she's already moving on from her broken marriage - Shriver has bought a new $US10 million ($A9.38 million) home in Brentwood, California - not far from the estate she shared with Schwarzenegger during their marriage, according to TMZ.com.
Schwarzenegger, who has four children with Shriver, could even exceed his legal obligations and give his soon-to-be ex-wife the majority of his Hollywood fortune in their upcoming settlement, a source told Radar Online.
The settlement proceedings will be overseen by a private judge, the source added, in order to prevent details of the pair's marriage from leaking to the media.
