Rihanna and rapper A$AP Rocky were caught having an intimate exchange on the set of a music video they are shooting together Thursday in New York City.

The duo are cast as lovers in the visuals that accompany the song Work, and they were photographed kissing passionately and displaying chemistry at the video shoot. The 25-year-old singer and 24-year-old rapper were very convincing in their roles even when the cameras weren't rolling, according to Hollywoodlife.

After the intimate photos of Rihanna and Rocky went viral, a source told the website that the entertainers are very close friends, but they are not dating.

"He's like a brother to her, they're cool," the source said.

Another source said the pictures just showcase Rihanna's flirty personality and she was just being herself. The insider also revealed that the rapper and pop singer have an arrangement of sorts in terms of their special relationship. 

""Rihanna is not Mother Theresa, she is more mother f***er. She is definitely not afraid to be sexual. Just look at all her photos she posts," the source said. "There is no dating relationship happening between the two, but they are definitely sleeping with each other. So that can obviously lead into things more romantic."

Rumors circulated that the Harlem native and Bajan beauty were dating even before the new photos hit the Web. They allegedly started their romance during Rihanna's Diamond tour, for which A$AP was the opening act from March through May. Rihanna helped fuel the rumors by posting his lyrics on her Twitter page various times.
