Gossip Girl TAYLOR MOMSEN ignites outcry after boasting of her switchblade collection AND the deadly blade she loves the most!

The tawny blonde thesp and sometime rocker revealed she collects shivs – even taking her fave blade everywhere!

"I have a knife collection," Taylor told UK Metro. "I have my favorite black knife with me all the time. It’s a switchblade.

"It relaxes me to flick it. I close it and open it.

"I flew from New York to LA and still had a couple of knives in my purse. I thought I took them out, but I opened my bag in LA and they fell out," she confessed.

"I was like ‘holy s**t.’"

But her slight off-hand remarks have landed the 16 year old wanna-be punk rocker in hot water with Britain’s MAMA — Mothers Against Murder and Aggression – a support charity that helps survivors after family members were violently murdered.

A MAMA spokesperson called Momsen "warped" and said she needs to "get a brain".
