Sir Tom Jones has taken a break from his mentoring duties on The Voice to sing at Havana's 16th annual Cigar Festival.
Cigar enthusiasts paid more than 1.1 million US dollars (£657,000) for six handmade Cuban humidors at the gala event to close the festival, which was held for a 16th year.
Sir Tom was among the celebrities invited to the auction and sang three songs for attending guests, including his signature It's Not Unusual.
He said he has been smoking Cuban cigars since the 1960s, but had never visited the country before.
Officials said this week that sales of Cuban cigars rose 8% last year. Proceeds from the auction were to go to Cuba's state-run health-care system.
