Pop star Lady Gaga said on Friday she and Kanye West decided jointly to cancel their Fame Kills tour, and she will embark on her own headlining concert series soon while West plans to drop out of the spotlight.

It was a mutual decision, Gaga said as she arrived for Billboard Women in Music Event where she received this years Rising Star award.

Kanye's going to take some time off. But the good news is that I'm going on tour in a few weeks.

Lori Ann Gibson, Gaga's longtime choreographer who was working on dances for the shows, claimed on her Twitter feed that creative differences between the Gaga and West led to the tour's abrupt demise.

The cancellation comes just days after the two pop stars announced the dates for an arena tour that was to kick off next month. Concert promoter Live Nation announced the cancellation news on Thursday and said refunds will be issued.

The cancellation comes on the heels of wave of negative publicity for West, following his interruption of Taylor Swift's award-winning moment at the MTV Video Music Awards in September.
