N.B. is the second studio album released by British singer-songwriter Natasha Bedingfield. It was released in the United Kingdom on 30 April 2007 through Phonogenic Records. Upon release the album was praised for Bedingfield's vocals and the fun theme to the records however some critics were disappointed noting that the material was not as catchy as her debut project, Unwritten. In the United Kingdom it produced two top ten hits, "I Want to Have Your Babies" and "Soulmate".
