George Michael ‘overwhelmed’ by birthday love

George Michael is "truly overwhelmed" by his birthday love.

The Careless Whisper singer, who turned 52 years old on June 25, broke his month-long Twitter silence on Thursday.

After posting a message to Adele wishing her a happy birthday on May 6,George disappeared from the micro-blogging platform.

But he returned to Twitter on Thursday expressing his gratitude.

"To my lovelies and fans around the world, thank you for all the birthday wishes, I am truly overwhelmed. I am looking forward to spending it with friends and family, thanks again, love The Singing Greek!" he tweeted.

Earlier this month, German magazine Bild claimed George admitted himself into Switzerland-based treatment facility The Kusnacht Practice to seek help once again for smoking excessive amounts of marijuana. Apparently he was smoking 25 joints per day before checking into the rehab centre.

Five years ago after pleading guilty to cannabis possession and driving under the influence of drugs, George served four weeks in prison.

And soon after being released from jail, he spoke of how the experience changed his mentality forever.

"I want to beat my drug addiction and lead a normal life," George is quoted by British newspaper The Sun as saying at the time. "I don't want to end up back in prison. It's a very horrible place to be. You're not considered a person when you're inside, you're just a number and that freaked me out."

Following his stint in jail, the pop star experienced a number of harrowing near-death events, including being unconscious for three weeks in December 2011 after falling ill with pneumonia.

In May 2013 George fell out of his moving vehicle while driving on a motorway in the UK, which resulted in a head injury.
