Wardrobe Malfunction Alert! Keri Hilson Goes Braless in Sheer Blouse

Singer flashes her nipples without knowing it while posing on the red carpet at an event

Look at those...um, shades?

Unfortunately, Keri Hilson is the latest celeb to fall victim to a wardrobe malfunction after having her headlights shown to the world when she decided to wear a sheer top sans bra.

Tsk. Tsk.

It didn't seem as though Keri knew that her ta-tas were on display as she was posing for photos at the Hennessy Wild Rabbit campaign launch event in New York City last night, but once the camera flashes went off, we were introduced to two surprise guests.

We don't know if she borrowed the see-through top from Rihanna (who's sure to have quite the collection), but we're pretty sure if Hilson decides to wear that long-sleeve shirt again, she'll consider covering up her perky friends as well.
