A YouTube DJ is feared dead after he leapt from a cruise ship into the sea following a row with his girlfriend on what should have been a dream trip.

Carlos Alberto Mota Candreva, 32, had posted videos to his social media pages from the ship as it sailed from Sao Paulo to Rio de Janeiro along Brazil's South Atlantic Ocean coast.

One clip shows the luxury cabin Carlos, who works as a programmer for a bank, had booked for the two-day New Year trip with model agency boss Vitoria Barbara Momenso, 27.

Carlos tells his followers: 'Still here at the Port of Santos, we are waiting to leave.

'Let's see what it will be, there's a party tonight. My suitcase hasn't arrived at the cabin door yet. We're here, enjoying it.'
