Rihanna 'responds to Taylor Momsen digs'

Rihanna has reportedly responded to Taylor Momsen's insults by telling her to "act her age".

Momsen apparently branded Rihanna "annoying" for wearing leather jackets but later said that she was misquoted.

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."

Momsen is thought to be concerned about Rihanna's response.
