Justin Bieber previews the title track to his new album Changes at acoustic gig in London

Justin Bieber gave fans and journalists a preview of his new album Changes - including exclusively unveiling the record's title track - at an event in London last night (Feb. 11). 

The superstar performed an acoustic version of Changes for the first time, as well as stripped-down versions of recent singles Yummy and Intentions plus a couple of his classics, ahead of the album's release on Valentine's Day this Friday (Feb. 14). Held at London's Indigo in The O2 Arena, Justin also answered fans' burning questions.

During the Q&A, Justin said he believed Changes had the most important message of all the songs on the album, similar to the title tracks of his previous records Purpose and Believe. Although Changes holds the most importance, Justin admitted his favourite track on the album at the moment is At Least For Now.

Lyrics to Changes include: “Some days I move like water, some days I burn like fire. Some days I wanna push further, some days I wanna do nothing. But I just wanna be the best me, even though sometimes, I forget to breathe. So that I can be the best for you. I’m going through changes, don’t mean that I’ve changed.”

Justin's latest single Intentions ft. Quavo is expected to be this week's highest new entry on the Official Singles Chart, on course for a Top 20 debut. Look at Justin Bieber's full UK singles and albums chart history
