Marg Helgenberger Is a Bikini-Rocking Babe at 55—See the Pic!

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.

After the trio had their fill of the sun, Helgenberger donned a gauzy white shirt and sunglasses and they headed off. 

Up next for the Emmy winner, who left CSI in 2012 after 11 1/2 seasons, is the CBS drama Intelligence. With all that crime lab experience under her belt, she now plays the director of an elite (what other kind is there?) team of government cyber-security agents.

Josh Holloway is her star operative who also happens to have a super-computer microchip in his brain that allows him to hack into any data center.

Helgenberger and Finkelstein have been together for close to three years now. She divorced Alan Rosenberg in 2009 after 23 years of marriage.
