PHOTOS: Fashion designer Marc Jacobs jets to Rio to celebrate his 49th birthday in the company of new porn star boyfriend Harry Louis,

Iconic fashion designer Marc Jacobs is the kind of man who has everything.

The best homes around the world, the most stylish cars and of course... a plethora of splendid clothes; in short, he'd be a bit of a nightmare to buy a birthday present for.

So it's lucky for the designer's friends that he treated himself to the gift of spending his 49th birthday yesterday with his Brazilian porn star boyfriend.

Like any sensible birthday reveler, the New Yorker has been stretching the big day out.

Jacobs, who split up with another Brazilian - Lorenzo Martone - last year, was spotted at the beach in Ipanema with his beau at the weekend.

But yesterday was the big day, and the excitement was obviously mounting when Harry tweeted:

Today is such an special day day... And it should be a notional holiday, at all countries, coz it's my baby's Birthday, lol. Luv U Marc ;) x

The 24-year-old, who now lives in London, is quite the smitten kitten, even announcing on his 'about me' blurb on Twitter that he loves 'his BF.'

Initially, the pair refused to confirm or deny reports that they were dating.

A photograph of the famed designer looking cosy at a Paris party with the adult film actor led to much-hyped speculation about the nature of their relationship.
