Singer and songwriter Pharrell Williams performed at Apple’s Campus today in Cupertino for an Earth Day celebration.
Apple CEO Tim Cook tweeted, “Thanks @Pharrell for an unforgettable Earth Day celebration!”, alongside a photo of him on stage.
Pharrell was first spotted with an Apple Watch weeks ago when he teased the device on The Voice and Instagram.
Apple kicked off this week with its environmentally responsibility report as well as a video highlighting its sustainability efforts. Today, in celebration of Earth Day, Apple added a green leaf to their logo at retail stores.
Apple is also gearing up for the launch for their new category products, thus the Apple Watch. Though the Apple Watch has not been launch but some celebrities are wearing theirs.
