X Factor winner Alexandra Burke has left the UK for warmer climes with fellow contestant Ruth Lorenzo.

The singer, who scored the 2008 Christmas number one with 'Hallelujah', headed to Mauritius from Heathrow airport with close friend Lorenzo yesterday.

'Hallelujah' also became the biggest-selling single of 2008 and set a new record for digital sales.
