Christy Turlington Modeling in NYC and Still Looking Awesome!

Christy Turlington's reign as a one of the world's hottest models ain't over yet ... based on this shot of her walking the dogs.

47-year-old Christy was a total smoke show as she took a couple of Great Danes out in Manhattan. Yeah, this was all for a photo shoot ... but we'll bet she looks pretty close to this on an average day anyway.

Gigi Hadid and Kendall Jenner have something to shoot for ... in 20 years.
