Top Shop and BHS owner Philip Green has splashed out some four million quid to get Destiny's Child to perform at his son's bar mitzvah.
The girls will perform on the second night of the family's three-day celebration. Opera star Andrea Bocelli performs on the first night. A brand-new synagogue has been built for the occasion.
Green previously spent £5 million on his wife's 50th birthday party, with Tom Jones and Rod Stewart performing. He is worth around £4.85 billion.
