Taylor Momsen's latest target to get a mouthful is pop star Rihanna, ahead of her London gig with her rock band The Pretty Reckless.

The famously outspoken star, 17, accuses the singer, 22, of being a 'rock wannabe'.

Taylor let rip; "People think pop is rock and the lines are getting blurred. Now Rihanna's wearing f*ckin' leather jackets and it's really annoying".  She went on to say that her look is that of a 'high-class hooker'.

Is the teenager hardcore and rock 'n' roll enough to judge others? We think possibly so.

"I dress for myself," Taylor told Spin Magazine. "Clearly, it's provocative, but it makes me feel good. And if the only reason it makes someone uncomfortable is because I'm 17, then that person's a scumbag because it shouldn't matter... I've had a lot of bad experiences, and whether that's from sex or drugs or something else, they are adult experiences that would fuck anyone up."

We are all looking forward to going and meeting Taylor tonight, when she performs at the O2 Islington Academy. We have backstage tickets to meet her in person! Will be VERY interesting!
