Adele is currently facing a tough decision after allegedly receiving proposals from Kate Moss and Michelle Obama to sing at their upcoming birthday parties. Since the dates are only a day apart, Adele will have no choice but to choose whether she'll favour the supermodel or The First Lady.

Moss will be turning 40 on January 16 whereas Obama will turn 50 the following day.  "Moss asked her team first to find out how much it would cost to get Adele to perform but Michelle then also invited her to sing alongside Beyonce at the White House. With Adele's fees, she could make £3 million in 72 hours if she flies from Kate's to the States," claimed an insider.

Health juice tycoon Vivien Imerman once said that Adele could charge up to £100,000 a minute.  It means that one set containing 5 songs can cost as much as £2.5 million. The South African juice magnate had an idea of Adele's rates after attempting to book the singer for his daughter's wedding.

Adele has not yet made a public appearance after singing James Bond theme 'Skyfall' at the Oscars last February. Nonetheless, the 'Someone Like You' singer did not stop in performing at private events and given her rate, such type of ventures have proven to be lucrative.
