Taylor Momsen hates sharing a toilet.

The singer-and-actress admits that there are huge differences between her role in US Drama series 'Gossip Girl' and touring with her band The Pretty Reckless, particularly when it comes to matters of hygene,

She said: "The f***ing port-a-potties-on a movie set, you don't deal with that!  Sharing a toilet with 50 bands is pretty nasty."

The 17-year-old star had no problem with making the transition from TV to music, but admits it could be harder for her fans to accept.

She told Interview magazine: "I'd say that the challenge isn't on my end, actually. I've been singing and writing songs my whole life, but people didn't know that. It's up to the public to transition to that reality."

The blonde beauty also thinks her group's album 'Light Me Up' is quite "dark", but reflects how she sees life.

She explained: "It's not really a happy record; if anything, it's sad...the words are definitely coming from me, and reflect my personal views on certain situations. I write about what I know, what I live, what I observe. Darkness is a subjective word; it depends what your viewpoint is and how you live life."
