Judging by these bathing suit photos, Maria Shriver must be doing a lot of yoga to help cleanse the stress of her troubled marriage.

The 56-year-old journalist and writer attended the Kennedy family reunion in Cape Cod with her children, looking radiant in a trendy one-piece black bathing suit and showing off her amazing figure. (She later added a cool black cowboy hat.) With Rihanna, Beyonce and more rocking the one-piece look, will this kick off a trend?

Shriver filed for divorce from her now-estranged husband Arnold Schwarzenegger in July 2011, two months after it was revealed Schwarzenegger had fathered a child with former household staffer Mildred Baena fourteen years prior. Although, they're now supposedly on good terms.
