The latest episode of the new season of Glee aired last night in the USA and saw the cast tackle Ke$ha's 'Tik Tok'. 

The whole show was featured around teen drinking and was aptly titled, 'Blame It On The Alcohol'. Rachel Berry, played by Lea Michele, decides to throw a house party as her two gay dads are away for the night, and the whole cast descend on her living room to play spin the bottle and sing songs. 

Back at school, the Glee club perform Ke$ha's 'Tik Tok' in front of their entire student body and the cocktails Rachel Berry gives them beforehand to calm any on stage nerves return for an encore. Watch the great clip here:
