Ri-Ri & Associates - Rihanna is the ultimate chart queen. With 13 No. 1's already under her belt it's easy to overlook collaborations that added to her epic aura of cool. While some did land the Bajan beauty at No. 1 some are actually under-the-radar diamonds. Check 'em out. —Jon Reyes(Photo: Christopher Polk/Getty Images for CBS Radio Inc.)

'Run This Town' With Jay Z and Kanye West (2009) - This trio would be the ones to deliver the ultimate “Roc Anthem,” paired with a video that was packed to the brim with militant imagery. While it didn’t get to top the charts, it made it all the way to the No. 2 spot. Ye must have been tight.(Photo: Kevin Mazur/WireImage)

'Livin’ a Lie' With The-Dream (2007) - Featured on The-Dream’s debut album, this album cut was absolutely angst ridden with a superb delivery by Ri-Ri. Even though it included some of the same “eh eh”’s that made “Umbrella” so contagious, “Livin’ a Lie” is near classic.(Photo: Johnny Nunez/WireImage)

'Live Your Life' With T.I. (2008) - T.I.’s pairing with Rihanna would give the Atlanta rapper his second and last No. 1 — it would be Rihanna’s fifth chart topper. As pop-glittery as the single may be, it's a testament to T.I.'s massive appeal and Rihanna’s ability to take anyone with her.(Photo: Kevin Winter/Getty Images)

'Fly' With Nicki Minaj (2010) - “Inspiration on steroids” would be another name for this track off Nicki’s Pink Friday. Though the pair would collaborate on Rihanna’s Loud album with “Raining Men,” it didn't quite recapture the epic-ness of this amazing hook.(Photo: Johnny Nunez/WireImage)

'Take Care' With Drake (2011) - Their second time working together would get us this stellar record. You would think that “What’s My Name” would make it on here, but the depth and genuineness of “Take Care” overshadows that calculative intention of “What’s My Name.”(Photo: Jeff Gross/Getty Images)

'We Found Love' With Calvin Harris (2011) - A worldwide renowned DJ and Rihanna get together and we get one of the ultimate party records of the past decade. We dare you not to jump up and down when those Calvin Harris synths blast through the speakers.(Photo: FilmMagic.com/FilmMagic)

'Love the Way You Lie' With Eminem (2010) - Eminem took a moment to really delve into domestic abuse and the perils that relationships who are plagued by it go through. Adding to the track's effect is Rihanna's on-point vocals.(Photo: Kevork Djansezian/Getty Images for MTV)

'All of the Lights' With Kanye West (2010) - What would My Beautiful Dark Twisted Fantasy be without this track? What would it be without Ri’s vocals? Kanye’s ode to stardom and celebrity hit the mark with this one.(Photo: Kevork Djansezian/Getty Images)

'Hard' Featuring Jeezy (2009) - This rough around the edges track would be a Top 10 hit for Rihanna. Though it failed to go to the top of the charts, it still manages to show Rihanna in top form on a club track. Plus, it’s one of Rated R’s finer moments. (Photo: Jeff Kravitz/FilmMagic)

'Hate That I Love You' With Ne-Yo (2007) - This single off Good Girl Gone Bad shows a very nascent voiced Rihanna cuddling alongside the mic with the singer-songwriter. Though it is the first time these two would be on the mic together it wasn’t the first time they collaborated together. “Unfaithful,” “Take a Bow” and “Russian Roulette” are all Ne-Yo penned tracks.(Photo: Scott Gries/Getty Images)
