Justin Bieber 'agonised' after hip injury

London, June 1 (ANI): Justin Bieber's mini-tour of Europe has reportedly hit a stumbling block after the teen star injured his hip.

The singer landed in Norway this week on May 28, to kick off a promotional trek for his upcoming album 'Believe', and to perform a string of secret shows as he travels the continent, the Daily Express reported.

However, Bieber woke up in agony on Thursday and took to his Twitter.com page to inform fans about his setback.

"Dear world... (I'm) being told I have to tweet to tell you what's up. I'm grumpy. Just woke up. Being honest... I pulled something in my hip yesterday," he tweeted.

The 18-year-old singer has, however, vowed to press ahead with his next stop in Paris, admitting time with his guitarist and musical director Dan Kanter had cheered him up.

"Dan Kanter's smiling face has made me feel better. It is so nice to spend time with Dan Kanter... PARIS Here we Come," he added. (ANI)
