Reese Witherspoon is a mother now and she likes to do what all mothers love- spend time with their children. The actress recently posted a picture of her son, Tennessee, and her enjoying a relaxing Sunday on a hammock. She and her four-year-old son were somewhat matching as they wore blue on top and white on bottom. In the background one can see floating balloons that spell out "FIESTA." Now these may be some fun decoration for the yard or they may be leftover from some previous party.
