After announcing a new US tour last week, British singer/songwriter Lily Allen [ tickets ] has freed up most of her calendar to allow herself more time in the recording studio.

The affected dates include most of the 19 shows Allen had lined up for May and June, save for a choice few. Following her April 29 slot at the Coachella festival in Indio, CA, Allen will still tackle shows in Seattle, Los Angeles, New York, and Charleston, SC, as well as her June 15 appearance at the Bonnaroo festival in Manchester, TN. Details are included below.

"I want to give my best to every audience I play to but, at the same time, I am itching to get back in the studio to start recording these great new songs, to keep things fresh for the audience and for myself," the singer said in a press statement. "I am not falling apart at the seams, I am not suffering with exhaustion, I am not pregnant, and I am not going to rehab. I will be here in America, promoting the album and also starting to write the second album, which I am beyond excited about."

The postponed dates have not yet been rescheduled, but Allen's publicist said the shows will be made up "later in the year."

Allen is touring behind the US version of her debut album, "Alright, Still," which surfaced in January and features two bonus tracks: "Nan You're a Window Shopper" and "Smile (Version Revisited)," remixed by DJ Mark Ronson.

The album--several cuts from which are currently streaming at Allen's website--entered The Billboard 200 album chart at No. 20 upon its US release.
