Pop star Duffy is relieved she looks nothing like her twin sister KATY - because her sibling is such a troublemaker.
The Welsh singer fears the media would mix the two Duffy girls up if they were identical - and the Rockferry singer would be dubbed a party girl.
The singer, real name Aimee Ann Duffy, says of her fraternal twin, "She's a bit of a troublemaker, she's partying all the time; if we looked the same I would get into so much trouble."
