Cameron Diaz showed off her toned arms and legs yesterday while out for a walk in NYC. She returned to the US just a few days ago after taking off from London's Heathrow airport with her good friend Gwyneth Paltrow. The girls enjoyed a week of fun in England, with Cameron meeting up with Jude Law and both blondes joining in on Stella McCartney's birthday celebrations. Now that Cameron's back in the US, a reunion may be in store for her and ex Alex Rodriguez. He's looking at a few free months, since the Yankees were eliminated from the playoffs. Cameron, however, may be called back to work as production on her What to Expect When You're Expecting continues.
