residency The album's lead single, "
I Kissed a Girl" was released in late April and subsequently soared up the charts. "I Kissed a Girl" was a commercial success. It topped the
Billboard Hot 100 chart, becoming the 1000th chart-topper of the rock era. The song has since become a major worldwide hit, and along with the United States, it has topped the charts in more than twenty countries, including Australia, Canada, Ireland, and the United Kingdom. The second single, "
Hot n Cold", made it onto the chart after the album came out due to digital downloads. It was released as a single in early September, and peaked at number three on the US charts, making it Perry's second consecutive top five single. On November 14, the song became Perry's first number one on radio airplay. It is officially one of the ten best-selling digitally downloaded songs of all time after its initial run. "
Thinking of You", the penultimate single, was originally planned to be the first single from the album, but was scrapped for "I Kissed a Girl" due to latter song's surge in popularity. "Thinking of You" received a video in late April 2008, but the video was removed from YouTube and replaced by a new video after the single was re-released as the third international single from the album. Perry shot the second video with director
Melina Matsoukas in the first week of December 2008. The video for the single was released on December 23, 2008. The track peaked at number twenty-nine on the
Billboard Hot 100 on the week of February 12, 2009 where it remained for the next two weeks before declining to number thirty-one in its seventh week on the chart. "
Waking Up in Vegas" is the fourth and final single from the album. It went for radio adds on April 21, 2009, in the US. It was released to Australian radio on March 23, 2009, where it became the fourth most added song in its release week. Perry performed it on
American Idol in May, resulting in a surge of sales for the song. The music video was shot by
Joseph Kahn during March 2009 in Las Vegas and officially premiered on the
iTunes Store in the US, and Australia on April 28, 2009. It peaked at number nine on the
Billboard Hot 100, becoming the third top-ten single from the album.
