Taylor Momsen’s Break from Hollywood

Right now, searches for "Cindy Lou Who" are spiking as we rewatch The Grinch for the holidays.

But when fans look up the actress, Taylor Momsen, they are often stunned by the transformation.

How did the innocent girl from Whoville turn into the hard-rocking frontwoman of The Pretty Reckless?

The answer lies in the intense pressure she faced during her teenage years on the set of Gossip

Girl. Taylor Momsen wasn't just "rebellious"; she was a young actress trying to

find herself in a very demanding industry. She was cast as Jenny Humphrey at

just 14 years old. In the beginning, Jenny was the sweet, innocent little sister.

But as the show exploded in popularity, the writers steered her character down a much darker path.
