British pop star George Michael has returned to Twitter.com after a year-long absence and vowed to put the troubles of 2013 behind him. The singer logged off the social networking website last January (13), and went on to endure a nightmare year which reportedly included a two-month stint at a clinic to treat anxiety issues, and a horrific freak accident in which he fell out of a car on a motorway in May (13). He was subsequently rumoured to be retiring from music before announcing a surprise comeback this month (Jan14). Michael has now returned to Twitter.com for the first time in 12 months, and asked fans to forgive him for the problems he suffered last year (13). He writes, "Hello my lovelies!!! A belated happy new year to you all!... Firstly, I can only apologise from the bottom of my heart for worrying you for so long with my silence... Suffice to say that 2013 was a year that I am glad to put behind me and that I hope you can forgive me for... Symphonica the (new) album is ready to go, and I hope it rekindles memories of the nights we spent together over the last few years."
