《Hot N Cold》是Katy Perry的第一张录音室专辑的第二支单曲，歌曲MV讲述的是男友在婚礼上悔婚的故事。这张《One of the Boys》是当时作为流行新人凯蒂·佩里(Katy Perry)的处子专辑，在Billboard 200专辑榜上榜首周，这张专辑就以4万7千张的单周销量名列本周榜单的第九位。

在唱片业日益萧条的时代，能够获得第九名的成绩对一位新人来说已经是相当不易的了。对于Katy Perry来说，她的这张专辑一发行就能够得到这么多歌迷的响应还是因为她此前先行打榜的单曲《I Kissed a Girl》的大受欢迎。在近几周的Hot 100单曲榜中，这首歌不断攀升，继上周获得亚军之后，本周又超越了Coldplay的《Viva La Vida》，夺得了Hot 100单曲榜的冠军。
