Former first lady of California Maria Shriver was recently spotted on the Cape Cod water front revealing a physique impressive enough to put the Governator Arnold Schwarzenegger himself to shame.

The 56 year-old American journalist, sporting a black halter neck swimsuit, showed off her tight body while accompanying the Kennedy group on their yearly summer vacation in Nantucket, according to Daily Mail.

Shriver was also joined by her offspring, which included 22 year-old Katherine and 18 year-old Patrick.  The latter child has been following in dad's acting footsteps as of late, as he had landed a role alongside Twilight's Taylor Lautner in the Adam Sandler comedy "Grown Ups 2," which recently wrapped on location in Boston.

Patrick recently tweeted an earlier picture of himself in Nantucket as a kid along with his cousins and siblings, and wrote the following:

"I'm the cutie crying in the middle of the photo."

It is reported that the clan has been spending a majority of their time jetting, speed boating and cycling around the beautiful six acre Hyannis Port waterfront that they have been occupying. The resort was originally owned by Rose and Joseph Kennedy, who have since passed.

The family and astonishing property had recently played host to famous country singer Taylor Swift, 22, who is currently dating Connor Kennedy, 18, the son of the late Mary Richardson Kennedy and Robert F. Kennedy Jr.

Maria Shriver is the niece of John F. Kennedy and the daughter of Eunice Shriver.
