Apple's product launch event on Tuesday was filled with celebrities and high profile attendees. U2 closed out the product announcement with a performance, while celebs including Will.i.am and Dr. Oz were spotted in the crowd.

Singer Gwen Stefani also made her presence at the event, too.

Stefani posted this image to Instagram and Twitter, showing her with Dr. Dre on his swanky private plane, on their way to the Apple product launch event. Cue the insane jealousy.
