On December 5, 2006, Ciara released her second studio album, Ciara: The Evolution. According to the singer, the title of the album is "about so much more than just my personal growth - it's about the evolution of music, the evolution of dance, the evolution of fashion." The source of the album's creativity such as the sound and edge comes from Ciara in general. Ciara: The Evolution became Ciara's first number one album on the U.S. Billboard 200 and second on the Top R&B/Hip-Hop Albums charts with sales of more than 338,000 becoming her highest first week of sales to date. The album went on to be certified platinum by the RIAA in the United States, within only five weeks of its release, and has sold 1.3 million copies according to Nielsen SoundScan. It sold over two million copies worldwide.  The album's international lead single, "Get Up", which features Chamillionaire, reached number seven in the United States and gained a platinum accreditation. It reached number five in New Zealand. The song was used for the film Step Up (2006) and featured on the film's soundtrack. The album's US lead single, "Promise", reached number eleven on the Billboard Hot 100 and became her third number one single on the Hot R&B/Hip-Hop Songs chart. "Like a Boy" was released as the second international single which reached within the top twenty in the UK, Finland, France, Ireland, Sweden Switzerland, and also in the United States. The fourth and final single from the album, "Can't Leave 'em Alone", reached number 10 on the Hot R&B/Hip-Hop Songs chart and number 40 on the Billboard Hot 100. The song became Ciara's fifth single to peak in the top in New Zealand, peaking at number 4. The song achieved moderate success in other international markets.  In support of the album, Ciara went on her first headlining tour in October 2006. The tour went to seventeen different clubs in cities throughout the United States. The tour was met with mixed to positive reviews; critics were divided regarding the pre-recorded backing tracks and remarked that Ciara was slightly under-prepared to host her own headlining tour, but ultimately praised her energetic choreography. In August 2007, she headlined the Screamfest '07 tour with fellow rapper, T.I.. Critics praised her performance for her gracious dancing and being able to command a sold out arena. Ciara, along with Chris Brown and Akon, was a support act for Rihanna's Good Girl Gone Bad Tour in the United Kingdom. She made a guest appearance on "So What" by Field Mob. The single went on to become a top 10 hit on the Billboard Hot 100. She also appeared on Tiffany Evans' single "Promise Ring". The song achieved little success on the Hot R&B/Hip-Hop Songs chart.  In addition to her music, Ciara made her acting debut in the MTV Films production All You've Got in May 2006.
