Rihanna Channels a Gothic Alien inBooty-Baring Lace Outfit atiHeartRadio Music Awards--Take aLook!

Just when you thought Rihanna couldn't surprise you when it comes to her outfit choices, she shows up to the first annual iHeartRadio Music Awards in Los Angeles wearing this. Keeping with her outrageous and attention-grabbing style, RiRi donned a full-length, see-through black lace dress that showed off her black undies and killer curves.

 She accessorized the look with a leather jacket, cross jewelry and a very interesting hairstyle that seemed straight out of a Sci-Fi movie. Oh, did we mention the green lipstick? Although the Barbados beauty caught us off-guard with this one, we have to admit there's really no one that could even attempt to pull this off. The singer may have decided to attend the awards last minute.

Without any details as to what she was referring to, Rih tweeted this morning, "I might throw on a dre$$ and pump through doe!" Well, she did throw on a dress (if you can really call it that). Rihanna also found herself running late because of traffic. The 

iHeartRadio account tweeted, "Here's a LA story for you: TRAFFIC. @Rihanna is actually stuck on the 405 Freeway on her way to the #iHeartAwards!"
