SHRIVER WARNING: BEWARE GREEKS BEARING GIFTS!

Glowing after her much-needed vacation in Europe with the kids, MARIA SHRIVER – who presided over the Special Olympics ceremonies in Athens – got giggly as a schoolgirl while confiding to a close pal that she fielded a surprise marriage proposal from a Greek tycoon…just like aunt JACKIE KENNEDY, who wed legendary gazillionaire shipping magnate ARISTOTLE ONASSIS!
 
“Maria was blown away,” said my source.
 
“It really gave her an ego boost.
 
"But she says she won’t consider remarrying until all the kids are out on their own.”
