Katy Perry Talks Releasing New Song With Rihanna

Katy Perry may be ready to collaborate with her good friend and fellow singer Rihanna.

Perry, the 29-year-old singer and songwriter, has had a public friendship with 25-year-old pop star Rihanna and recently revealed their plans to release a song together.

"We have to do the best song ever," Perry recently told Los Angeles radio station 102.7 KIIS FM. "Beyond that, I think we'll definitely get around to it, and when it happens, you are going to know."

Perry has maintained her friendship with Rihanna for years and revealed her feelings about the singer in an issue of Elle U.K. earlier this year.

"I love her [Rihanna] and every time I see her, I'm reminded of the light that she has," Perry told Elle U.K. "There's a lot of dark in this business...I know a lot of people out there with the most detrimental entourages - they are the root of their demise."

Earlier this year, Rihanna and Perry were the subject of reports that the latter disapproved of a reconciliation with ex-boyfriend Chris Brown who physically abused her in 2009.

"They're barely talking and ever since the couple reunited, there has been tension between them..." a source previously told The New York Daily News' Confidential. "Katy fears Rihanna is making a huge mistake and doesn't want to be part of it."

Rihanna previously laughed off rumors that she and Perry were at odds over the former giving her friend relationship advice.

"Katy Perry can date anyone she wants," Rihanna said in a Now Daily report last May. "Besides, who the (expletive) am I to say anything? I could never give relationship advice to anybody!"

An Us Weekly source reported that Rihanna and Perry reunited with one another last May after some time spent apart.

"They hung out like old times and were catching up," the source told Us Weekly last May.
