Rihanna has completely "fallen for hot" Josh Hartnett.
The 'Umbrella' singer - who was spotted "kissing and cuddling" Josh in a New York nightclub last month - has confirmed the pair are dating.
Speaking at the World Music Awards in Monte Carlo, Rihanna said: "I would be lying if I told you we were not more than just friends. I have so fallen for him, he is lovely.
"He is so hot and he is really sweet to me. When we hang out it feels right - even though it's still pretty new."
The pair first sparked romance rumours four weeks ago when they seen intimately enjoying each other's company as they shared a table and drank Dom Perignon champagne at New York nightspot Pink Elephant.
Josh reportedly decided to make his move on the 19-year-old R'n'B beauty after watching her perform in her racy stage outfits at the Nokia Theatre in Times Square the night before.
The 29-year-old actor refused to deny rumours he was romancing Rihanna and dodged questions about the couple's steamy nightclub embrace during a subsequent TV interview.
When asked if he had been kissing Rihanna, Josh stuttered: "Whoa, whoa, whoa! No, no, no. Come on you guys! This is, uh, we weren't supposed to talk about these things were we?"
Josh has previously been linked to 'Black Dahlia' co-star Scarlett Johansson and supermodel Helena Christensen.
Rihanna was recently said to be dating 'Transformers' star Shia LaBeouf.
