Adams released his eleventh album internationally on 17 March 2008. It is called "11". The album was released in the US at Wal-Mart and Sam's Club retail stores on 13 May 2008. The first single released from the album was "I Thought I'd Seen Everything". Adams did an 11-day, 11-country European acoustic promotional tour to kick off the release of the album. The album debuted at number one in Canada (making it his first album to reach that position since "Waking Up the Neighbours" in 1991) as well as reaching number two in Germany. In the United States, the album charted at number 80. Following the release of the album, the full-band tour starts during the summer: on some dates in the United States he shares the stage with the rock band Foreigner and in others with his friend Rod Stewart.
