Former Trump campaign chairman Paul Manafort spent $18,000 on a karaoke machine and assorted equipment for his home in the Hamptons, according to recent court filings.

Manafort's wife Kathleen paid for the karaoke costs by transferring money from Cyprus-based bank accounts, which Manafort is accused of illegally concealing from authorities to evade taxes.

Manafort has been charged with bank fraud and is awaiting trial in Virginia, set for July 31.

Former Trump campaign chairman Paul Manafort spent $18,000 on a karaoke machine and related equipment for his vacation home in Bridgehampton, New York, according to court documents released ahead of his upcoming Virginia trial.

The court filing includes invoices from New York Sensoryphile, Inc. to Manafort's wife, Kathleen, show that she was billed for approximately $8,000 and then around $10,000 later, for the machine itself, plus song packages, microphone stands, installation costs, and even a fancy touchscreen remote.

The full invoices for the karaoke machine and other services from the same vendor for the Manaforts' Hamptons house were entered into the court record as stipulations, facts of the case that both the defense and prosecution agree to.

According to court documents, Kathleen wired money from multiple bank accounts based in Cyprus to pay for the karaoke machine. The charges brought against Manafort accuse him of evading taxes on substantial assets held in a number of foreign bank accounts, many of them based in Cyprus.

"Manafort used his hidden overseas wealth to enjoy a lavish lifestyle in the United States, without paying taxes on that income," the February indictment filed in the federal court for the Eastern District of Virginia reads, laying out the charges against him.

Additional stipulations filed by both Manafort's and Mueller's teams include more details from Manafort's financial records, including the purchase of several Range Rovers and an invoice from an antique rug store.

Opening arguments in Manafort's Virginia trial are scheduled to begin July 31.
