In preparation for the North American release of her sophomore album, British pop singer-songwriter Lily Allen has announced plans for West and East Coast concerts this spring. The 15-date run picks up April 1 at the House of Blues in San Diego, CA, and closes out April 22 at Phoenix Concert Theatre in Toronto, ON.

The coast-to-coast jaunt includes an April 2 concert at The Wiltern in Los Angeles, CA, an April 11 performance at First Avenue in Minneapolis, MN, and an April 19 gig at the new House of Blues venue in Boston, MA, among other dates.

The tour-closing show is currently the only date booked for Canada. Ticket onsale dates and prices have not yet been announced.

Allen is promoting her second studio album, “It’s Not Me, It’s You,” which is slated for a North American release on February 10. The album is a follow-up to the acclaimed 2006 debut “Alright, Still,” which peaked at No. 20 on the Billboard 200 driven by the hit single “Smile.”

This is the musician’s first U.S. tour since 2007, when Allen cancelled the majority of her concerts due to personal fears that her performances were not up to par. “I am tired, but more than that I don’t think I have been giving my best performances recently,” Allen explained in her MySpace blog. “I have been getting really drunk because I’ve been so nervous about doing bad shows, and I don’t want people spending money on going to see a show that isn’t the best it could be.”
