Classic Gaga: the singer wore what would become her signature hair bow, along with a simple satin dress and hot-pink heels for the Nokia 5800 launch party. The star told MTV that she made the accessory herself, using inexpensive hair extensions: "I tied it up in a bow, and then you can just bobby pin it to your hair."
