LBB (Little Black Bikini) Showdown: Rihanna vs. LeAnn Rimes (POLL/PHOTOS)

Bikini Bodies: Guess Who?!
Can you match the celeb with her bikini?
Trend: White Bikinis
Stars step out in white two pieces!
If there are two women capable of igniting a bikini trend, it’s these two. LeAnn Rimes and Rihanna love to strut their stuff in skimpy swimsuits, and this weekend, they did it in a similar fashion.

The pop singer and country crooner both wore what we’re labeling a LBB (little black bikini).  Rihanna, 24, was vacationing in Hawaii while LeAnn, 29, traveled to Cabo San Lucas, Mexico with her husband Eddie Cibrian, 38, to renew their vows.

No doubt these women know how to rock teeny bikinis, but who rocked the LBB best?
