PHOTOS: Miss USA Rima Fakih - Red Hot In Yellow Bikini

She's got her sash, but where's the tiara?

Reigning Miss USA Rima Fakih posed in a skimpy yellow bikini at Mandalay Bay in Las Vegas on Thursday, and RadarOnline.com has the sexy shots!

Fakih, 24, made history in May when she became the first Muslim and the first Arab-American to be named Miss USA.

Rima was born in Lebanon, but was raised in New York. She moved to Michigan with her family in 2003.

Later this summer, Rima will be competing in the 59th annual Miss Universe Pageant, which will be broadcast live from Vegas on August 23 on NBC.
