N.B. is the second studio album released by British singer Natasha Bedingfield. It was released in the United Kingdom on 30 April 2007 through Phonogenic Records. In the United Kingdom it produced two top ten hits, "I Wanna Have Your Babies" and "Soulmate". In January 2008, the album was released in the United States and Canada under the name Pocketful of Sunshine with new packaging and an alternative track listing featuring only six of the original songs. The US version's title song became a top-five hit whilst the lead single, "Love Like This" with Sean Kingston, became a top-fifteen hit. US critics said that the album felt inorganic and awkwardly assembled.
