RIHANNA is taking LEONARDO DiCAPRIO as her plus one to a family wedding next month.

The couple – who have so far kept their relationship low key – will go public at her cousin’s bash in Barbados.

An insider said: “Afterwards Rihanna and Leo are going to spend a few days by themselves on a yacht.” Meanwhile Ri-Ri is spending a lot of time at Leo’s LA mansion.

Friends said: “It’s like she’s practically moved in. Leo has been sweet and cordoned off little areas for her in the home that are just for her, like a smoke room.”
