The New Yorker, 39, has been sentenced to between five and 10 years in prison for stealing millions of dollars from concert promoters and party planners by posing as a booking agent.
McEaddy, who also pretended to be in charge of Lady Gaga, Rihanna and several other celebrities, pleaded guilty to 21 counts of grand larceny and fraud, among other charges, according to Manhattan district attorney’s office.
The scam involved McEaddy and 48-year-old Sylvester Vincent Carroll, of New Jersey, promising event producers a performance by a major recording artist, pocketing large deposits and not delivering a show after being paid.
The scheme is thought to have started in 2010 with a fake bookings for Rihanna for concerts in Rio de Janeiro
Carroll, who also pleaded guilty, was sentenced this month to three to nine years in prison.
Manhattan District Attorney Cyrus Vance Jr said the two stole around $3.7 million (£2.2m) from party planners around the world.
He added that the scheme started in 2010 when the duo took $825,000 (£488,000) from a Brazilian company that believed it had booked Rihanna for concerts in Rio de Janeiro.
