Rihanna has been spotted partying in London twice so far this week, despite doctor's orders to stay away from clubs and late nights.

The 23-year-old was forced to cancel gigs in Sweden two weeks ago when she was taken to hospital and put on a drip after contracting a flu. She was then told by a doctor that she was burning herself out and needed to stay at home and rest.

RiRi was also told to stop having so many late nights, drinking and partying, but it seems just a fortnight later she is back to her old habits. She was spotted on Sunday night leaving central London club Whisky Mist and last night was seen arriving at Cirque Du Soir club at 3am.

The 'We Found Love' singer is currently in the UK to complete the rest of her 'Loud' tour dates at the O2 Arena.

Check out the pics of RiRi's partying in the gallery below. Should she slow down her wild lifestyle?
