Leann Rimes has apologised to fans for posting an ill-advised tweet about Wednesday night's (03Dec14) race protest in New York City.

The country singer was preparing for her live performance at the 2014 Rockefeller Center Christmas Tree Lighting Ceremony in the Big Apple as thousands of activists took to the streets to protest a grand jury decision not to indict the New York police officer who was caught on camera choking African-American Eric Garner.

The 32 year old seemed discouraged by the news of the protests and tweeted, "Wow, riots are sad tonight coming out of a joyous place. #peaceatchristmas #prayersforall."

She later returned to Twitter to apologise for her remarks, adding, "My heart is in the right place. I am sad for everyone tonight. Those who are wronged, those who are struggling, those who are heartbroken. My heart is with you. I wish peace for all. I apologize if my understanding of the ny (New York) protests were taken in any other way. It was what was being relayed to me and reported."

Rimes sang her new festive hit I Want a Hippopotamus for Christmas at the Christmas in Rockefeller Center ceremony.
