Natalie Portman is rumored to be dating 'Saturday Night Live' funnyman Andy Samberg.The 'Closer' actress met the comedian a year ago when they co-starred in a spoof rap video which poked fun at her 'Little Miss Perfect' reputation when she hosted the popular US comedy show 'Saturday Night Live'.The pair's alleged romance blossomed after Natalie split from long-term boyfriend Gael GarcĂ­a Bernal. Samberg's co-star Kenan Thompson said: "If Andy is dating Natalie, I'm extremely jealous."The 'V for Vendetta' actress is currently working with FINCA International, an organisation which gives small loans to impoverished people in developing countries. Natalie, 25, said: "Getting this loan enables them to start their own business out of their own house and be with their children. It changes the whole system."If a woman can't tell her child, 'I can feed you tomorrow, I can pay for your school', then what happens? What do they do? What do they choose?"It's really trying to reach the poorest of the poor and offering banking services to them."
