Singer Lily Allen has postponed the next leg of her US tour, saying she wants to work on her second album, BBC News Online reports.


The 21-year-old, whose album Alright, Still reached the U.S. Top 20, recently complained she was “bored slightly” at attempting to crack the U.S. market.

Allen said she was tired and “itching to get back into the studio.” She will perform a handful more dates but has called off 20 shows in May and June. Those concerts will be rescheduled for the end of the year.

On her MySpace blog, Allen joked, “I thought that being a pop star meant going out getting trashed with famous people and sleeping in all day. The fact that this is not true has come as a huge disappointment to me, and as a result I am throwing the towel in.”

The tour had also seen some controversy after she reportedly insulted

George Bush and called southern Americans “backwards.”
