Snow stalls Susan Boyle

Scottish singer Susan Boyle was late for a surprise appearance onstage with her idol Donny Osmond in London on Sunday after heavy snowfall hit the capital.

The star, who shot to fame on TV show Britain's Got Talent, was due to perform with Osmond during his concert with sister Marie at the O2 Arena, but her flight into the city was delayed due to the wintry weather.

The former child star introduced Boyle before a rendition of This Is The Moment, the song they recorded together for Boyle's last album, but had to re-order the setlist after discovering she had not yet reached the venue, according to The Daily Express newspaper.

Boyle arrived in time to appear onstage with Osmond during the concert.

The I Dreamed A Dream hitmaker isn't the only star who was affected by the heavy snowfall - boy band Blue, singer Katie Melua, Irish group The Script, and former Culture Club frontman Boy George have all been caught up in travel chaos.
