Natalie Imbruglia and Dizzee Rascal walked arm in arm in London today. The pals stuck together to fight off the freezing weather. Natalie has been subject to rumours of a romance with millionaire hotelier Justin Hemmes, but she has insisted they're just good friends. She's been busy in Oz after her guest judge stint on The X Factor in the UK, but she's back on our turf and spending time with UK-based friends like Dizzee. He's in the running to be named your favourite British solo act of 2010, and 2011 is already shaping up nicely for the rapper, as he'll headline Belsonic music festival in Belfast next Summer.
