Saucy Emily Ratajkowski Walks Her Dog in Her Underwear (3 pics)

The 25-year-old supermodel turns heads with her sexy appearance in public!

The model and actress looked just a tad chilly as she stripped down to lacy underwear while exercising her pooch in New York.

However, instead of just being an exhibitionist, the 25-year-old was actually filming an advert for DKNY in the US city.

Em certainly attracted attention though as she walked down the street with her furry friend in just lingerie and chunky boots.
