The new member, Ewen, was flown to the United States to film the music video for single "About a Girl" mere days after Buchanan had left the group. "About a Girl" reached number 8 in the UK, during a truncated promotion schedule due to Berrabah flying to Austria for treatment for nervous exhaustion resulting from the line-up change. In late 2009, "Wear My Kiss" was confirmed for release in February 2010 as the third single, with the album, originally set for a late November 2009 release, delayed until March 2010. "Wear My Kiss" debuted and peaked at number 7 in the UK, making "Sweet 7" the Sugababes' first album since "Taller in More Ways" to contain at least three top ten hits. The album debuted and peaked at number 14 in the UK but was critically panned due to the loss of an identifiable sound, soul and originality stemming from Buchanan's departure.
