He has nearly two million fans and a book deal. But Boo isn't a reality TV star, actor or a pop singer - he's a pet dog.
The five-year-old Pomeranian has the fame most celebrities dream of after amassing 1.79million fans on social networking site Facebook.
And Boo is also a hit with the ladies. He attracted the attention of Hollywood stars including Khloe Kardashian, who posted a picture of the dog on her blog last year and singer Ke$ha, who Tweeted that Boo was 'her new boyfriend.'
Since then, Boo's Facebook page, launched in 2009, has gone viral, receiving thousands of new fans a day.
His owner, who has concealed her identity and location in the U.S. and uses the pseudonym J.H Lee told Time:'My friends loved looking at pictures of him.
'We started the first Facebook page as a joke.'
Boo shot to fame when he realised the key to looking so good in photographs is a great haircut.
The canine's unique look is down to an happy accident - his long hair was so knotted, it had to be shaved off.
