Is it Katy Perry vs. Rihanna? It looks like "Dark Horse" singer has spoiled her friendship with RiRi. Katy Perry did a major dissing at Rihanna's boyfriend Drake's cost. She called the rapper 'soft' in a radio interview. Perhaps, that's the last thing a man would want to be called.

Will Rihanna give a piece of her mind to Katy Perry after this controversial comment? Katy and RiRi have been good friends but have also ignored the dissing sessions at each other's cost. However, now that the slime-green angel dragged Drake in the middle of the court, Rihanna might wear her fight suit and battle it out with Katy.

In an interview in "The Breakfast Club" on Power 105.1, Katy talked about her "Dark Horse" collaborator Juicy J and she had all the nice things in the world to say about the artist.

However, when she compared Juicy J to Drake, things turned nasty.

"[Juicy J] is such a sweet, genuine guy. [He's] an amazing hard worker," said Katy, reporting by HollywoodLife.com.

"I've worked with a lot of people that I've done little pieces on songs and not that they've got ego, but Juicy's the kindest. He's like the most kindest, sympathetic, sweet - I don't wanna make him out like to be softer than Drake..."

However, Katy Perry tried to correct things up.

"I love Drake. He's like my secret diary."

Katy's words for Drake might be well-meant, but it has to be seen how RiRi would react to this.

Fans are hoping that Rihanna will not get mad Katy's words.

Rihanna and Katy were not cool with each other after the Chris Brown quarrel.

However, both Katy and Rihanna went past the fight and attended a birthday party of a mutual friend at 1Oak nightclub in NYC on April 25.

Fans are hoping that Katy's well-intentioned comment does not spoil things between the singers.
