Rihanna red hair singer wig david letterman late show jacket nyc

Rihanna has a smokin' hot career (not to mention a hot bod!) but even with her electric red hair flat-ironed and slightly longer, we're still not digging it.

The R&B princess made an appearance on Letterman this afternoon, and she was kind enough to pose for pics and sign autographs for dozens of fans camped outside the studio. Eh, she's such a sweetheart, we're willing to overlook the hair don't and send her some virtual kisses. XOXO!
