Her fifth album, Rejoice, released in November 2007, included original songs, two of which were written by Gary Barlow. It reached number 3 on the UK pop charts, surpassing albums by the Spice Girls and Girls Aloud.

In October 2008, Jenkins released Sacred Arias, her final album under Universal Music. Shortly after, she signed a US$10 million (£5.8 million) deal with Warner Music, reported to be the largest in classical recording history at the time.

Warner Music Era and Collaborations

Her first album with Warner Music, Believe, was released in October 2009 and featured collaborations with Andrea Bocelli, André Rieu, and Chris Botti. Jenkins promoted the album on UK television and performed “Parla Più Piano” (from The Godfather) at events including Children In Need Rock the Albert Hall alongside cellist Julian Lloyd Webber. In 2010, she reprised the song at A Concert for Heroes at Twickenham Stadium, and also performed on the Argentine television show Susana Giménez.

Her subsequent albums included Daydream (2011), This is Christmas (2012), and Home Sweet Home (2014), the latter marking her debut with Decca Records. In 2015, Jenkins expanded into progressive rock by contributing spoken word vocals to “A Perfect Life” on Steven Wilson’s album Hand. Cannot. Erase.

In 2012, Jenkins competed on the American television show Dancing with the Stars, finishing in second place. In addition to her musical endeavors, she has performed for British troops in Iraq and Afghanistan, and supported numerous charitable causes.
