Jennifer Lawrence Admits She Didn't Know How to Use a Miracle Mop!

Jennifer Lawrence continues her promo tour of her new movie Joy at a special luncheon on Monday (December 14) in New York City.

The 25-year-old actress, who was joined by director David O. Russell and others, chatted about her new movie with Extra and talked about playing Home Shopping Network star Joy Mangano, who created the famous Miracle Mop.

“Bradley Cooper had to show me how to use it. They had one growing up. His mom used to watch QVC, I was just a redneck in Kentucky,” Jennifer said. LOL!
