The two stars are confirmed for next month's ceremony

Rihanna and Taylor Swift have been confirmed to perform at the 2013 Grammy Awards.

The star-studded ceremony, which takes place in Los Angeles on 10 Feburary, will be celebrating its 55th Annual Awards with hot performances from the two pop sirens.

Also due to perform at the prestigious event are the Black Keys, Kelly Clarkson and British folk band Mumford & Sons.

This year's Grammy nominees include Carly Rae Jepsen, who secured two nominations for Song of the Year with Call Me Maybe and for Best Pop Solo Performance.

Justin Bieber praised Carly for being up for two gongs, despite failing to be nominated for any himself.

Manager Scooter Braun expressed his anger at the snub, saying: "I just plain DISAGREE. The kid deserved it. Grammy board u blew it on this one. The hardest thing to do is transition, keep the train moving."

However, Justin took the news a little more gracefully and said on the Ellen De Generes show: "I was looking forward to [possible Grammy nominations], but I know it will happen one day.

"I'm so young, I'm only 18. I'm just blessed to be able to do what I love every day."

Meanwhile, new reports suggest Chris Brown wants to duet with Rihanna at the upcoming awards ceremony. Watch this space. We're sure it'll be one massive performance, whatever RiRi does.
