The end of “Exquisite Enigmatic Us,” the last session for today at TEDGlobal 2013, is appropriately rounded out by a former student of psychology, English pop singer Natasha Bedingfield. (Did you know she studied psych at university?) Popular for her hits “Unwritten” and “Pocketful of Sunshine,” Bedingfield performs “These Words” and debuts a newly written song, “I Like You.” As Bedingfield jokes, “They say ‘love the one you’re with,’ but liking the one you’re with is harder. If you like the one you’re with, hold onto them tight.” Sporting some very awesome black-and-white-dotted skirt-pants, Bedingfield closes with her Grammy-award-nominated hit, “Unwritten.”
