Rihanna will not only be taking the stage with Coldplay at the Grammy Awards on [article id="1677516"]February 12[/article], she'll also join a number of A-list EDM talent for a charity event set to go down the same day.

The singer, along with deadmau5, Calvin Harris and Sebastian Ingrosso of Swedish House Mafia will perform at the House of Blues in Los Angeles, with all proceeds from the show going to the Children's Orthopaedic Center and an artist's program at Children's Hospital Los Angeles. Tickets for the charity show go on sale this week for $1000. (More information on ticket sales and the charities is available on its official Live Nation page.)

February 12 is shaping up to be quite the busy day for a number of the artists slated to perform at the charity concert. Rihanna is up for a handful of Grammy Awards including Record of the Year for 2010's Loud. Grammy-nominated deadmau5 is also up for a number of awards, including Best Dance Recording for his album Raise Your Weapon.

Meanwhile, Harris, who produced Rih's chart-topping Talk That Talk single "We Found Love," will join his collaborator at the House of Blues.

" 'We Found Love' is the most successful thing I've done ever," [article id="1677718"]Harris told MTV News[/article] recently. "It's not strictly a song by me, obviously, it's by Rihanna. She sings it.

"It was great to work with her," Harris continued. "No one could have taken it as far as she did. You can't escape it here [in America]. I've heard it a lot. I've heard it probably more times today than I did when I was mixing it, which is a good thing."
