Katrina Kaif has a bikerchik look in Blue. The actress has a stud pierced her lip, dreadlocks and tattoos all over her arms. Says a source, "Katrina was excited about her look as it's differnet from whatever she has done so far."

But one thing that gave Katz nightmares was her hairdo! The dreadlocks that she sported could cause a lot of damage to her hair. "She'd go for a hair wash immediately after the shoot," says the source.
