In Pinks music video for the song, "Get the Party Started", it shows Pink as she makes her to a club. When she arrives at the club, she is wearing a large gold necklace. Upon her arrival, she stands in the background, while some of the extras do some break dancing etc. Her necklace is clearly visible when she's in the background. When it's Pinks turn to dance, she steps up, but her necklace magically disappears! Then when they go back to a shot of Pink in the background, the necklace reappears!
