The first English single from the album, "I Like It", which features the rapper Pitbull, was released on 3 May 2010 in the U.S. and became a success, reaching No. 4 on the "Billboard" Hot 100. The song was also featured in the MTV reality series "Jersey Shore". "Cuando Me Enamoro" was released as the lead Spanish single from the album, and became the theme song of the Mexican telenovela of the same title, produced by Televisa. The song debuted at number eight and number twenty-five on the U.S. Latin Pop Songs chart and the U.S. Hot Latin Songs chart, respectively. It became his twenty-fifth top ten single on the U.S. "Billboard" Hot Latin Songs chart and after four weeks of its release date, it became his twenty-first No.1 song on this chart. In January 2011, the album's third English single, "Tonight (I'm Lovin' You)" broke into the top ten on the "Billboard" Hot 100, also reaching No. 4. The song was released only for digital download in the United States but was featured on some editions of "Euphoria" in Europe and some Asian areas. The song became Iglesias' first number one on the U.S. Pop Songs and Radio Songs airplay charts. A remix version of the album track "Dirty Dancer" was released as the fourth English single and became his ninth Hot Dance Club Play chart topper, tying with Prince and Michael Jackson as the male with the most No. 1 dance singles. Further, "Ayer" served as the album's third Spanish single and seventh single overall. The Euphoria Tour took Iglesias across the U.S., Canada, the U.K., and several European countries. One of the tour's legs took him to Australia, while fellow artist Pitbull joined him as an opening act. Prince Royce also served as opening act during the tour's second leg across North America.
