After being flown over from the States, Lopez and her entourage are to be accommodated in a number of London hotels for her set that is to last just 40 minutes.

A source told the Daily Mail regarding the party, "It will be wall-to-wall billionaires in there.

"Andrei and Aleksandra (his wife) are both very great fans of J-Lo so Andrei put the call in and personally put the offer to her. She accepted immediately.

"She will sing for about 40 minutes - not bad money for the work."
