A brunette has become an internet sensation after launching a blog on which she posts a photograph of her impressive cleavage daily.

The woman has never revealed her face, leading to speculation about who she is and whether or not Alicia Young is even her real name, the Daily Mail reported.

Her site - Los Escotes De Alicia , which translates as Alicia's Low-Cut Tops - is believed to be based in Valencia, Spain, and has already got over three million hits since its launch in November.

The mystery blogger, who claims to be 31 and is believed to be of British origin, posts photographs of herself while engaged in a number of activities, from eating and drinking to reading and hanging Xmas decorations.

In each image, she is seen wearing tight or revealing tops - and sometimes nothing at all, covering her modesty with only her hands, or props like hats and books.

Occasionally her bosom is penned with words, names and phrases.

Each post is accompanied by a Spanish text explaining what she's been up to each day, like hanging out with friends or doing "a little bit of work."

Young also uses her Twitter page to post cleavage shots, and it is believed that she hopes to eventually secure a lucrative deal for publication.
