As America’s sweetheart Reese Witherspoon celebrates her 47th birthday, Peopleworld celebrates her transition from the front of the camera to behind the scenes. A very happy birthday for actress-turned-producer Reese Witherspoon, who celebrates her 47th birthday today, no doubt in the loving company of her three children, Ava, Deacon and Tennessee. Birthday’s this time of year for mum’s such as Witherspoon are a double celebration, given how close it is to Mother’s Day – which Witherspoon also celebrated as a mum herself and with her own mother, Betty Reese.
