BEIJING, Nov. 28 (Xinhuanet) -- Adele has announced her first tour since 2011, with a string of European dates in support of her record-breaking new album, "25."

The album sold a record 2.4 million copies in its first four days in the U.S., while in Britain it sold 730 thousand copies in its first week.

One reason for the huge sales may be that Adele declined to make her album available through music-streaming services including Apple Music, forcing listeners to buy it either digitally or at stores.

The British singer announced that she will play venues in Britain and Europe starting February 29th in Belfast, Northern Ireland.

The singer will then take her Arena show to Dublin, Manchester, London, Glasgow and Birmingham before heading across Europe in the spring.
