An accountant who defrauded celebrity clients including Rita Ora, Matt Dawson and Martin Bayfield has been jailed.
Andrew Munday, 38, used money from the fraud, totalling at least £3.35m, to buy houses, Star Wars memorabilia, and an executive lounge membership at Tottenham Hotspur.
Munday, of Earls Close in Northampton, admitted nine counts of fraud.
Prosecutor Simon Davis told Northampton Crown Court he “had been living a lie” to fund a lavish lifestyle.
Munday was jailed for five years and eight months.
The business where he worked at the time, Blue Cube Business, has since stopped trading.
As well as buying houses, he also bought football memorabilia, and designer jewellery.
In a victim statement, the singer VV Brown said Munday had “ruined a lot of people’s lives” and left “deep scars” in relation to trust.
Munday caused a loss to former X Factor judge Ora’s company of nearly £2.4m during the fraud campaign spanning seven years, the court heard.
He had previously been declared bankrupt after building up gambling debts.
Nigel Edwards QC, defending, said a “severe gambling disorder” was the “principal driver” of Munday’s actions but he had done his “level best” to turn his life around.
Speaking after sentencing, Det Sgt Richard Barnett, from Northamptonshire Police, said: “Munday abused his position of trust, which has caused significant financial and emotional harm to all of the victims.”
