The We Found Love singer, 23, who comes from the Caribbean island, will headline the party for the UK's Global Radio boss Ashley Talbot at the luxurious Sandy Lane hotel, and the 52-year-old music mogul is expected to be in attendance.
Boyband The Wanted are also expected to perform.
A source told British newspaper the Daily Star: 'The government paid Rihanna £1.25 million to perform at Barbados Carnival in August as she is obviously their biggest export.
'Everyone is very excited to hear that she'll be back again so soon and plenty of the islanders are hoping to catch a glimpse of her in town, even if they can't get into the party.'
