Pharrell appeared at Apple's headquarters and Tim Cook thanked him.

Apple didn't want to celebrate a day like yesterday (Earth Day) with a makeover in its stores or with its section in the App Store . To end the day, the company brought one of its celebrity friends to its offices in Cupertino , who was the first to be seen in public with the pink band Apple Watch ; we are talking about Pharrell.

The singer and songwriter, also known as Skateboard P , celebrated with a concert as part of the environmental responsibility initiatives that Apple has been promoting for some years, but which have undoubtedly intensified in recent months.

Pharrell was first seen sporting the Edition on the music show " The Voice " in early April, becoming the first on the list of artists and celebrities who have managed to get one of the models before all the other users, even before Apple's own developers.

The singer later posted pictures of his Apple Watch on his Instagram profile, where others like Katy Perry continued the campaign to promote the device. Tim Cook quickly responded by tweeting his appreciation for the singer's participation.

Apple has already begun updating the order status for the wearable, informing users about its shipment. Pharrell , meanwhile, is preparing for his tour, which begins in June and will take him to countries such as Ireland, Singapore, the UK, Belgium , and even Japan in early August.
