During a photo shoot, never, ever, ever wear a Bluetooth cell phone thingy. It reinforces that geek image.
(Harald “Bluetooth” Gormsson (Old Norse: Haraldr blátǫnn Gormsson, Danish: Harald Blåtand Gormsen) (probably born c. 935) was the son of King Gorm the Old and of Thyra Dannebod. He died in 985 or 986 having ruled as King of Denmark from around 958 and King of Norway for a few years probably around 970. And yes, the bluetooth phone things are named for him.)
