Cameron Diaz needs to check herself out in the mirror before she leaves her house more often!

We spotted the blond-bombshell and her crazy doo on the set of her new film Wichita filming in Boston, Massachusetts this morning.

I'm not sure who's in charge of costumes for this movie.. but the black biker boots and yellow sundress aren't really working for me!

Tom Cruise was also spotted on set today.. his hair and wardrobe seem a bit more.. put together!

What do you think?!

    

Beantown has been buzzing with MASSive amounts of A-list celebrities the past few months. First Mark Wahlberg and Christian Bale.. then Ben Affleck and Blake Lively.. now Cameron Diaz and Tom Cruise are beginning to film their new action-comedy Wichita..

Cameron looks absolutely beaming in her yellow sundress.. and Tom looks very Mission Impossible.. with gun in hand..

Check out more pics from the set below..

      

What are you smiling about??

Cameron Diaz looked super happy as she left her New York City apartment this afternoon.  The actress flashed us her model smile as she strolled on by with her laptop in hand.

Cammie was recently at the Independent Spirit awards, not sure why since she hasn't been in a movie since What Happens in Vegas (meh) but she will hit screens again this year with the sentimental My Sister's Keeper.

    

We spotted Cameron Diaz rocking some skin-tight jeans and a beanie cap as she got in some serious shopping in downtown Manhattan today.

The lovely Cam was in a great mood, chatting with photographers and laughing and smiling.

But she remained coy when asked about the whereabouts of her Brit BF, Paul Sculfor.

We like Cameron since she ditched Justin Timberlake...she's much nicer to work with.

    

Love's in the chilly air!  We spotted Cameron Diaz and her boyfriend Paul Sculfor walking hand in hand through Manhattan this afternoon. Cammie, who was in town for the premiere of Shrek: The Musical, shopped with her beau at Aero furniture store in Soho before taking a cab back to their hotel.

      

We spotted Cameron Diaz yesterday who must have been a little ball of energy!  Camie was leaving her pilates class in Los Angeles with a coffee in hand when we ran into her.  Pilates and coffee?!  My gosh, Cam, you probably have enough energy for the next week!

     

We spotted Cameron Diaz in Manhattan yesterday.  Cameron and her friend stopped by a salon and treated themselves to manicure, maybe they went all out and got a mani/pedi (one of my favorite made up words in the English language)? Camie D is back to rocking the long, blonde locks and I think that's her best look. She looked cute, but casual; Justin Timberlake who?!

       

Has Cameron Diaz lost her marbles and shaved off all her hair?!  She and Britney may have an ex-boyfriend in common but one thing they do not share is a panache for shaving their head when they get a little stressed. Cameron's chrome dome is due to a role in her new movie My Sister's Keeper. Cameron plays a mom whose daughter (Sofia Vassilieva) looses her hair after being treated for leukemia and shaves her head in support; Abigail Breslin plays her sister.

       

Cameron Diaz hit the red carpet looking radiant last night, marking her return to Hollywood since the tragic loss of her father two weeks ago.  Cameron was at the Village Theater in Westwood to premiere her new movie What Happens in Vegas with co-star Ashton Kutcher.  Also on hand for the event were Lake Bell, Diablo Cody, Eva Longoria, Soleil Moon Frye (Punky!) and Bai Ling, cuz what's a red carpet with out that ding bat?

       

Cameron Diaz's ex-boyfriends, Justin Timberlake and John Mayer, came out to show their support at a memorial service yesterday in honor of Cameron's late father Emilio.  Emilio Diaz, only 58,  died suddenly last week of pneumonia and yesterday the Diaz family had a "celebration of life" at Mahe in Los Angeles to honor him.  Guests did not dress in drab black, but rather wore brightly colored attire and gave toasts to honor their friend and relative.  Cameron issued a statement saying "His humor and spirit will always live on in our hearts."
