Pharrell Williams has been in contact with Kanye West since he was admitted to hospital last month.

The rapper confirmed that he reached out to friend and collaborator West via text message and he knows Pharrell is supporting him 100 per cent.

Pharrell was appearing on US radio station Hot 97 when he was asked by host Ebro Darden if he had any words of support for Kanye, who on Thursday night was seen out for the first time since being hospitalised last month.

“I'm sure you've seen what's happened with your compadre and all of our friends Kanye West and the pressure of his life and what's going on - do you have any kind words for Kanye? Have you been able to talk to him?” asked Darden.

“Oh I've texted him already,” replied Pharrell. “He knows my sentiment.”

Pharrell then made an impassioned plea for people to help make the world a nicer place.

“I think everybody should just you know, we all should just be wishing people well,” he said. “We need it, there's strength in numbers and with all this like division out here in this country it's like, they're beating us."

Pharrell and Kanye go way back, and the pair have collaborated on a number of tracks. Last year, Kanye tweeted a number of compliments for the musician, including glowing praise for Pharrell's single Freedom (“Beautiful song, incredibly shot”) before adding, “Skateboard P is the God” (Skateboard P being one of Pharrell's nicknames).
