Singer Nelly Furtado wanted to strangle producer Timbaland during their collaboration on her album LOOSE - as the rap mogul walked out on her every time he got bored. The Canadian star admits Timbaland is a "genius", but she wishes he could work on his social skills. She says,"It was almost Pavlovian. If he's not feeling what you are doing, he walks out of the room! "He's got a low attention span. Half the time I wanted to wring his neck, but that comes with genius, the social awkwardness."
