Now this right here is what we call a power pair. At last night's iHeartRadio Music Awards in LA, Rihanna and Jennifer Lopez got their BFF on backstage — and we couldn't be more obsessed. Srsly. But what's more? They're both rocking epic '90s outfits. J. Lo took it back to her Jenny From the Block days in a form-fitting and fierce halter-neck Zuhair Murad dress teamed with stick-straight locks. Meanwhile, RiRi went goth-glam in Givenchy and Bantu knots, which we've loved since Gwen Stefani showed 'em off way back when. Ladies, nicely done. We want more of this duo. 

See Rihanna killing it in a spring twosie.
