Despite several rumors & tons of speculation, Hollywire can confirm that our favorite rocker chick Taylor Momsen will NOT be returning to Gossip Girl for the 100th episode special. 

We caught up with The Pretty Reckless singer inside her tour bus just before her show at the Hollywood Paladium on October 11th, where she revealed she wasn't even aware of the show's upcoming milestone. 

"I won't, I'm 100% music all the time right now and it's awesome," Momsen told our own Katie Krause

The 18-year-old singer also told us she doesn't even have time to keep up with the the show's story lines while on the road.  "I have no idea what's going on," she admitted.  "You kind of live in a bubble on tour, I mean, there's a TV but you know you don't watch it... you don't really keep up with anything."
