Barack Obama's inauguration ceremony took place this past Monday (21st January) and saw performances from Kelly Clarkson and Beyonce, the latter of whom has faced a storm of criticism in the wake of allegations she mimed her performance of the US National Anthem.
This week the singer's producer Zedd confirmed her new album 'ARTPOP' is still being worked on and that the two plan to get back into the recording studio next month.
Lady Gaga will continue her 'Born This Way Ball' tour this evening (23rd January) when she plays the US Airways Center in Phoenix, Arizona.
