Robbie Williams has been admitted to a rehab clinic in the US after developing a dependency on prescription drugs.

His spokesperson Bryony Watts announced his decision to enter a treatment facility but refused to go into any further detail on the matter.

Robbie, who turns 33 today, spent time in rehab to help with alcohol and drug dependencies after leaving Take That in 1995.

Model Lisa D’Amato, who sold a tell-all story about Robbie to the News of the World at the weekend, revealed Robbie’s new problem: “It was clear he was struggling with his mind. He doesn’t drink, but he needs antidepressants to get him through the day. A lot of the time he seemed on edge.”

He has previously admitted to having an addictive personality and that his time in rehab last time didn’t help with that: “I’m still addicted to everything - if I play two games of table tennis I’ll be addicted to that.”
