Los Angeles radio station KIIS FM has announced their 2013 Wango Tango lineup, and Bruno Mars, Demi Lovato and Maroon 5 are just a few of the names on the bill for this year's live show, set for Saturday, March 11, in Carson, Calif.  

Mr. Mars is set to open the show, hopefully with his chart-topping hit 'Locked Out of Heaven,' and a slew of other performers are to follow. As we said before, 'Heart Attack' songstress Demi Lovato will perform (let's keep our fingers crossed for some new material!), as will 'Daylight' pop-rockers Maroon 5.

Additionally, the Ryan Seacrest-hosted show will include performances from 'I Cry' hip-popper Flo Rida, BRIT Award winner Emeli Sande, Black Eyed Peas frontman will.i.am, recently returned pop-punk outfit Fall Out Boy and Grammy-winning crooner Miguel.

'Ridin' Solo' singer Jason Derulo is also set to sing live -- we can't wait to see him back in action now that he's recovered from the traumatic neck injury that left him out of the loop last year -- as will 'The Way' newcomer Ariana Grande and the 'I Love It' ladies of Icona Pop. Electro dance trio Krewella will take the stage, as well, as will EDM table master Afrojack.

Bonus! Britney Spears will co-host the 2013 Wango Tango concert with Seacrest!
