Hollywood's Most Match-Perfect Couples

Every diva needs the perfect accessory! Marc perfectly balances his

sexy wife's neutral snake-print Monique Lhuillier dress and gold

jewels with a shiny khaki suit and cool shades while in Miami Beach.

Gwen and Gavin are the picture of rock star cool,

sporting black aviators, graphic T-shirts (an All Saints one for her!) and

dark bottoms while out in New York City.

Even a little snow can't stop this happy couple's stylish coordination! Donning his-and-her fur-trimmed coats – a toggle shearling number for Nick and a white puffer for Mariah – the lovebirds stay cozy in Aspen, Colo.

From their matching straw fedoras to their coordinating navy blazers and

blue jeans, Diane and Joshua prove they are in style sync as they

arrive in Saint-Tropez.

The low-key couple keep their style equally laid-back, rocking matching

white tops and shorts while grocery shopping in Santa Monica.

Well, that's one way to keep warm! Justinand his lady love snuggle up in matching black

jackets, plaid scarves and blue jeans for a lunch date in New York City.

Everything is over-the-top when it comes to the funny Brit and his

California Gurl! From the oversized shades to the shiny outerwear, Russell

and Katy make a statement of togetherness while arriving in L.A.

The new parents haven't tamed all their wild ways! Mason's mom and dad add

a pop of leopard to their stride – printed shorts for Kourtney and

matching spotted loafers for Scott – while strolling through New York City.
