Jay-Z Cancels Final Dates On 2009 US Tour

Jay-Z has scrapped the last three dates on his US tour due to an “unforeseen scheduling conflict”.

The rapper had been due to play in Lubbock tonight (November 17), New Mexico on Thursday (November 19) and Friday (November 20) in El Paso.

These gigs will now no longer take place, according to a message on promoter Live Nation's website.

The cancellation comes less than 24 hours after Jay-Z joined Rihanna on stage at a gig in London.

The rapper teamed up with the singer on two hits – 'Run This Town' and 'Umbrella' – as she showcased songs from her new album, 'Rated R'.

Jay-Z also made a special guest appearance at wife Beyonce's show at the O2 Arena on Sunday.
