Katy Perry, Rihanna Could Learn From These Killer Collabos

Catch Katy talking duets and more on 'MTV First' Wednesday at 7:23 p.m. ET on MTV and MTV.com!

Rihanna recently discussed the possibility of a duet with pal Katy Perry. Now, the “Part of Me” singer is weighing in on the collaboration talk.

During a conversation with Britain’s Radio 1, Perry confirmed Rihanna’s statement, saying that a collabo was imminent but added that they’re waiting for the right tune to come along.

“I want it to be like that Eurythmics and Aretha Franklin song ‘Sisters are Doin’ it for Themselves,’ not like [Shakira and Beyoncé's] ‘Beautiful Liar,’ ” Perry said. “I definitely want to do something that is so iconic. [Rihanna's] kind of busy too, we’re both busy, but we planted the seed two years ago. How disappointed would you be if that song came out and it’s no good? Sometimes you have to wait for greatness.”

She has a point: Whenever two pop stars come together, fans hope for extraordinary results. And Perry only upped the ante by tossing some (unintentional?) shade Beyoncé’s way. So to help the dynamic duo along, MTV News rounded up four awesome superstar collabos — ones for which both artists contributed equally — that we think fit Perry’s “iconic” criteria. Study closely, girls.

“One Sweet Day,” Mariah Carey/ Boyz II Men
The hit single about reuniting with a lost loved one in heaven paired two of the top acts of the ’90s at the peak of their careers. The result was, well, the biggest song ever. Carey and BIIM saw “One Sweet Day” spend 16 weeks at #1 on the Billboard Hot 100, the most of any song in the chart’s history. It also helped propel Carey’s fifth studio album, Daydream, to diamond status (10 million sold) in the U.S.

“Empire State of Mind,” Jay-Z/ Alicia Keys
“Empire” is a great collabo because both artists shine doing what they do best. The single features top-notch verses from Jay-Z, who sounds reinvigorated rapping about the iconic faces and places around his native New York. And Keys’ chorus and piano loop are so memorable and anthemic that there’d be no song without them. Combined, the two superstars capture the essence of New York City — and that’s no small feat. Jay and Alicia earned two Grammys for their efforts: 2011′s Best Rap/ Sung Collaboration and Best Rap Song.

“The Boy Is Mine,” Brandy/Monica
Brandy and Monica’s memorable duet spent 13 weeks at #1 in 1998, making it one of the 10 longest-running chart-toppers of all time. The all-girl collabo, which eventually won the pair a Grammy for Best R&B Performance by a Duo or Group, would probably serve as the best blueprint for Rihanna and Katy.

“N—as in Paris,” the Throne
“Paris” was one of the biggest slow-burn bangers of 2011. While most singles by superstars dial up massive top 10 debuts because of the avalanche of digital downloads, “Paris” took its time becoming a chart-topper. The song debuted at #75 in late August before peaking at #5 in January, which is to say the track pretty much owned radio throughout the fall and winter of ’11. On their Watch the Throne Tour, Jay and Kanye ended each show with “Paris,” sometimes playing the song as many as 10 times in a row. The hit song even made it to MTV News’ list of the Best Songs of 2011 .
