Hollywood heavy hitters traded cold fronts for sunny New Year's destinations such as Florida, Mexico and Hawaii -- and we couldn't be more envious of their sleek physiques and warm-weather duds.

Showing a lot more skin than we typically see from the "Big Love" actress, Chloë Sevigny spent some time in the surf while wearing a double-strap print bikini and cat-eye sunglasses in Miami.

We spotted another blonde, country singer LeAnn Rimes, in a very similar suit while vacationing in Mexico with fiancé Eddie Cibrian.

Meanwhile, Jennifer Garner said aloha to 2011 in Hawaii with the entire Affleck-Garner clan. The 38-year-old actress frolicked with her two daughters, Seraphina and Violet, in a fiery two-piece and white cover-up.

And don't forget to check out Kourtney Kardashian showing off her post-baby bikini bod on the cover of OK! Magazine.
