Taylor Momsen will be watching her mouth after she took on the wrong popstar...

TayMom got too big for her hooker shoes and mouthed off in an interview saying that she found Rihanna's rock n roll styling annoying and now she's dealing with the consequences of those actions.

According to Sugarscape, Rihanna was not going to take the comments lying down and got hold of Taylor's phone number to give her a piece of her mind.

A source said: "Rihanna did not take kindly to a 17-year-old making such rude comments about her, especially since they flooded the internet as soon as they were released.

“She got Taylor's number through a friend and called her up, telling her to back off and act her age. Rihanna is not the kind of person you want to mess with."

Do you think Taylor will be more careful now?

Rihanna looks amazing!
