'Glee' actress Amber Riley is set to sing at the Major League Baseball All-Star Game.

The 24-year-old actress - who is known for her powerful vocals as Mercedes Jones in the popular show - will perform the national anthem and a series of other songs shortly before the annual sports competition later today (13.07.10).

The starlet will take to the stage at the Angel Stadium in Anaheim, California this afternoon, ahead of the annual baseball game which takes place between National and American League players, as chosen by fans, players, managers and coaches.

Amber adores working on the hit musical TV show and despite spending hours with her co-stars, she admits they all work hard to remain on good terms with one another.

She recently said: "You know, we spend sometimes 14 hours a day with one another.

"We rehearse together, we sing together, we travel together, so we have to make an effort to get along with one another."
