Robbie Williams' mum Jan has urged fans of the troubled singer to show their support and send him letters - even though he can't receive them as part of his treatment.
Robbie admitted himself to America's Meadows rahab centre on his 33rd birthday, after revealing his addiction to prescription drugs, among other vices.
"When you go through something like this, the more support you get the better" Jan Williams told The Sun.
She said that she will take any letters that are written straight to Robbie, when she goes to visit him in Los Angeles.
As part of his treatment in rehab the ex-Take That singer is not allowed to use the internet or receive letters.
Meanwhile Robbie's dad has also spoken out about his son's progress, and claims that he'll be out of treatment quicker than expected.
"We are hoping to have him out of rehab soon" said Pete, adding "Rob has plenty of friends and family around to support him. I speak to him every day and he is in fine fettle. He is doing well."
Get well soon Robbie!
