Pop and country singer LeAnn Rimes [ tickets ] is about to kick off a busy summer tour schedule as she continues to support "Twisted Angel," an album that hit stores last October.

Rimes' itinerary, which focuses on the West, includes a mix of headlining dates at casinos and concert halls, as well as several festival dates.

"Twisted Angel" features single "Life Goes On," the music video for which is streaming at Rimes' official website.

Rimes, who attended a writing camp prior to making "Twisted Angel," worked on the album with producer-songwriters Peter Amato, Desmond Child and Gregg Pagani, according to Curb Records. She is credited with co-writing four of the album's tracks.

Rimes gained fame in the country and Christian music markets, but "Twisted Angel" leans more toward mainstream pop.

The GRAMMY^®-winning Rimes recently contributed "We Can," the theme song to MGM Pictures' new comedy "Legally Blonde 2: Red, White & Blonde," which stars Reese Witherspoon. Dianne Warren, who wrote two of Rimes' previous hits--"Can't Fight the Moonlight" and "How Do I Live"--penned the new track.

Now 20 years old, Rimes delivered her major-label debut, "Blue," when she was 13. The hugely successful set is certified quintuple-platinum for shipping five million copies in the U.S.

According to a press release, Rimes will release a Christmas album this fall. On August 25, she will issue an illustrated children's book titled "JAG," which she and her husband wrote together.
