N.B.

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. Bedingfield worked with a mix of new producers, including Mike Elizondo, Danja, and Greg Kurstin, and reteamed with her Unwritten collaborators, Steve Kipner, Wayne Rodrigues, Andrew Frampton, and Wayne Wilkins. N.B. represented a thematic shift, exploring relationships and the complexities of sharing one’s life.

Reviews for N.B. were mixed, with critics praising its ambition, production, and Bedingfield's vocal performance, while others criticized its uneven songwriting, lack of risk-taking, and weaker tracks. The album fell short of matching the success of her debut Unwritten (2004), peaking at number nine on the UK Albums Chart and receiving a Gold certification for sales exceeding 100,000 units, while attaining only moderate positions in international markets and failing to chart in several countries.

The album produced two top ten hits, "I Wanna Have Your Babies" and "Soulmate," with the former achieving moderate chart success. Follow-up, "Soulmate," released in July 2007, performed better internationally, reaching the top ten in several countries and earning a Gold certification in Germany. Following several delays, N.B. was reissued in North America under the name Pocketful of Sunshine (2008) with new packaging and an alternative track listing featuring only six of the original songs.
