Over the last few years, he has become one of the most recognisable faces in Hollywood and he's already a household name in the UK.
Gossip king Perez Hilton has steadily built up so many contacts in the celebrity world that he is now as famous as those he writes about on his hugely popular website.
But you would be forgiven for not recognising the 30-year-old as he has undergone an astonishing transformation over the last 12 months.

Perez has shed his formerly fuller figure in favour of a lean physique, which he hopes will soon resemble David Beckham's.
He told MailOnline: 'I'm not weighing myself, so I don't know how much I've lost. But I know my clothes fit a lot better.
'I've gone from a 46-inch waist to a 36-inch waist.
'My goal is not be skinny. I wanna be in good shape. I'd love David Beckham's body.'

Perez has revealed the secret that lies behind his dieting success - a lucky number.
He said: 'The only number that's important to me is five - and that's making sure that I work out five days a week. And I do. I'm very committed and it's all about consistency.
'It's been a months-long process, which began back in January. The first step was just eating healthy.
'In February, I started walking at least 30 minutes a day, five days a week. And in March is when I began working out at the gym with trainers.

'I have two trainers. They alternate weeks - I like the variety. We do a lot of cross training, weights, cardio, core work.
'I'm getting my meals delivered, six days a week. Thankfully, I have a cheat day!
'But, I honestly don't feel like I'm being deprived. The healthy food is yummy.
'Clichéd as it may sound, this is a change I've made for life. I'm excited to be healthy and fit.'

Spice boy: California-based Victoria Beckham gets to know Perez
It's certainly been a long journey. Four years ago there was no Perez, just Mario Lavandeira, a magazine writer with a passion for fashion and celebrity news.
Then he started a blog about celebrities under the name of Perez Hilton.
Back to the present, and Perez is preparing to travel to Liverpool in November, where he'll be the 'Digital Host' at the MTV Europe Video Music Awards - although he also has an ulterior motive.
He said: 'Maybe if I work out hard enough, I can find myself a cute English boyfriend soon.
'I've never been to Liverpool before. I can't wait!'
