Love was in the air during Venus Williams's US Open match Friday night in New York. And when Chelsea Clinton and Marc Mezvinsky weren't taking in Williams's win over Mandy Minella of Luxembourg in straight sets, they were kissing and giggling – like newlyweds should!
Just married in July
, Clinton and Mezvinsky are recently back from their honeymoon in an undisclosed locale.
