She is incredible. Beyoncé is the fastest selling album on iTunes since it's release a few days ago. How amazing is that? Omg. 'XO,' acts as the second video, following 'Drunk In Love.' Top models Jessica White and Jourdan Dunn make an appearance, and Jourdan also features in 'Partition.' which I think has to be my favourite video and song. 'XO' was produced by The-Dream, Ryan Tedder, and Beyoncé, with production by Hit-Boy. Another gorgeous video, beautiful concept, and stunning lyrics.
