OK magazine recently published a story suggesting that the 'Umbrella' singer and Usher were flirting and nuzzling at the Coachella Valley Music and Arts Festival over the weekend.
According to the publication, witnesses also saw Leonardo DiCaprio speaking to Rihanna, but said that she went home with Usher.
"They're having fun and hooking up," the reports suggested.
However, an insider has claimed that the story is false, reports Gossip Cop.
It was recently suggested that Rihanna has a number of half-siblings in Barbados from her father's past relationships.
The popstar's collaboration with Britney Spears, 'S&M', reached the number one spot on the US Billboard chart this week.
