Later that month , it was announced that " How to Be a Heartbreaker " would be released as the second single in the United States and the third single in the United Kingdom .

It peaked at number 88 in the latter country . Throughout 2012 , Diamandis travelled for The Lonely Hearts Club Tour , her second headlining concert tour , and Mylo Xyloto Tour headlined by Coldplay , for which she served as an opening act .
