We're quite used to seeing celebrities pop in and out of rehab in the wonderful world of Hollywood. I usually couldn't give a flying hoot about the likes of Lindsay Lohan's and Britney's checking in and checking out habits. But seeing Robbie Williams out and about made me smile. Good to see this cheeky chap enjoying an L.A nightclub with pals just one day after checking out of rehab for addiction to prescription drugs.
