Coldplay extend Wembley support

Both acts will now appear at Wembley Stadium in September

Girls Aloud and hip-hop star Jay-Z will now appear at both of Coldplay's Wembley Stadium tour dates in September, it has been announced.

The acts had previously only been booked to each play one of the two dates at the London venue, but will now share the support bill.

Coldplay's website also said London rockers White Lies would be providing additional support at both shows.

The band's UK leg of their tour begins on 12 September in Manchester.

The tour, which began in Florida in May, finishes up at Wembley Stadium on 18 and 19 September.

Coldplay announced earlier last month they would give away CDs of their new live album LeftRightLeftRightLeft at every remaining live show in 2009, as well as make it available as a free download from their website.
