As if more evidence was needed that Marg Helgenberger was a babe for the ages.

Add the former CSI star to the list of celebs ringing in the New Year in a warm, sunny place—and judging by this shot taken of her on the beach in St. Bart's Monday, there's no need to make a resolution about getting in shape.

Helgenberger, 55, was showing off her fabulous figure in a turquoise bikini as she enjoyed the ocean with boyfriend Alan Finkelstein and her 23-year-old son, Hugh Rosenberg. While not in the water, she smartly shielded her face from the sun with a brimmed hat.

The fair-skinned actress has obviously remembered her sunscreen over the years as well, because her porcelain complexion (and matching bod) is proof that tans are overrated.
