Her name is Pornchita Na Songkla, nickname Benz. She has been a top Thai model, actress and celebrity for a number of years. In her younger days she did some stunning photos.
Now days she does more TV show hosting and makes appearances at various events in Bangkok. Her look is different than most of the popular Thai celebrities. She has dark skin, big eyes and a wide smile. She appeared in a couple of Thai movies, Zapp (2006) and Jaew (English title MAID, released in 2004). In Jaew she plays a maid who is secretly a spy and she is pretty funny, something that comes easily to her because she is a fun and humorous person which you can see in most of her TV appearances.
But she has also had serious roles, like in one Thai TV soap opera where she played a black person. She's dark already, and they added body makeup to make her even darker. The effect was not very convincing but it served its purpose.
