Hollywood child star looks unrecognizable with exposed breasts and ripped six pack on red carpet… can you guess who it is?

She is a former child star who landed a memorable role in How The Grinch Stole Christmas at the age of six.

This actress, now 31, also had a regular role in the legendary high school soap opera Gossip Girls.

She was a multi-talented actress who also did modeling work. At the age of 14, she signed with the elite agency IMG.

Besides her work as an actress and model, she is also a musician: she is the lead singer of the rock band The Pretty Reckless.

It’s Taylor Momsen!

Momsen looked very different from the role of Jenny Humphrey, the character she played for five years on Gossip Girl, at the KidSuper’s Funny Business Comedy Fashion Show in New York on Monday.

The actress showed off her toned abs and breasts – which she covered with tape – as she stunned down the red carpet.

She wore a cool black jacket with gray stripes and matching pants for the fashionable event.

The pants had a belt and hung low enough to reveal a hint of underwear.

Taylor wore fashionable platform boots and her blonde hair was styled loosely.

She wore several necklaces, including one that reached her cleavage.
