Rihanna has responded to loud-mouth Taylor Momsen's comments last week that she finds her style annoying.

Taylor had said that she finds Rihanna's rock chick look annoying as she is not really into that style of music and doesn't make it either.

However, it seems Rihanna did not take kindly to this and tracked Momsen down to give her what for.

A source told Heat: "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."

This one could run and run. Are you team Rihanna or Team Taylor?
