Pharrell Williams has reportedly got engaged.

The rapper-and-producer recently proposed to his long-term girlfriend Helen Lasichanh and the delighted model-and-designer said “yes”.

According to website MediaTakeOut.com, The Neptunes star asked Helen to marry him “a few weeks ago” and the happy couple are planning to tie the knot next spring.

Pharrell and Helen have a son together they named Rocket.

The couple were seen at the New York premiere of new Batman movie ‘The Dark Knight Rises’ on Monday night (16.07.12) and Helen was sporting a huge diamond ring on her engagement finger.

However, GossipCop.com claims the pair have been engaged for about a year.

Pharrell has been busy recently working with young British pop star Conor Maynard at his studio in Miami, and Conor claims the N.E.R.D producer keeps himself busy during quiet times by customising his clothes.

He said: “When I was recording, he was always spray painting on his clothes and drawing on them, he’s a very creative person, he does some crazy things, he’s always drawing on his shoes – he creates all his own bespoke clothing for himself out of whatever he has on at any point.”
