Double take!

When Kim Kardashian and LeAnn Rimes hit the red carpet at Sunday's Grammy Awards in L.A., fashion critics wondered if perhaps the stars called each other the night before to coordinate outfits.

Kardashian, 30, who arrived on the arm of brother, Rob, showed up in a plunging shimmering bronze Kaufman Franco that had to be altered at the last minute to fit her famous derriere.

Nominee Rimes, 28, turned heads in a very similar gold V-neck design by Reem Acra.

The sexy stars might look nearly identical, but they have dramatically different Valentine's Day plans. The country singer and her fiance Eddie Cibrian are playing Wii and eating pizza with friends, while Kardashian has something more titillating in mind. In an ad for her eponymous fragrance, the lingerie-clad reality star reveals that she’s looking for an "extra, extra special" evening.
