Amy Winehouse has reportedly scooped one million pounds for an exclusive performance in Russia.
The Back To Black singer was flown by private jet to Moscow for the two hour set on Friday for a mystery Russian businessman, where guests included billionaire businessman Mikhail Prohorov and Sergei Kapkovym, head of the Russian Football Association, according to The Daily Mail.
Amy, 27, minded by 50 bodyguards, sang a selection of her hits from the top floor of a closed off shopping centre and was described as "fantastic" by one member of the crowd.
The Rehab singer was a guest at an exclusive £1,700 per night hotel in the city centre - but managed to attend the gig and return in a single day.
Amy, who has battled drink and drug problems and been through a difficult divorce from ex-husband Blake Fielder-Civil, has not performed a full solo concert since 2008.
She appeared on BBC One show Strictly Come Dancing last year, when she provided backing vocals for her 13-year-old god-daughter Dionne Bromfield.
She then performed four songs at a low-key event to mark the launch of her new line of clothing for designer Fred Perry in October.
Amy is set to perform a series of six shows in Brazil in January 2011.
