Rihanna is clearly not a woman to be messed with if the reports are true that she has hit back at Taylor Momsen.

Gossip Girl actress Taylor, 17, said in an interview that the pop star was a “wannabe rock chick”, which she found “annoying.”

Well now a source has claimed that Rihanna “did not take kindly to a 17-year-old making such rude comments about her,” and tracked down her phone number to tell her to “back off and act her age.”

“Rihanna is not the kind of person you want to mess with.” the source added.
