Robbie could leave rehab within days

Robbie Williams has "amazed" rehab staff with a speedy recovery, according to the star's family.

The singer checked in to the Meadows rehab clinic in Arizona twelve days ago for help in conquering an addiction to prescription painkillers.

Robbie's father Pete Conway confirmed that the 33-year-old has coped excellently with his treatment and could be home within days.

"Robbie is in good humour, cracking jokes and on good form," Pete told the Daily Star Sunday. "I'm extremely positive about him - he is doing well. I speak to him every day and he is in fine fettle.

"I am looking forward to flying over to the States to see Rob. We are hoping to have him out of rehab very soon. Rob has plenty of friends and family around to support him."

Another family source added: "It looks like he could be out in days - he has amazed Meadows staff with his recovery."
