Bruno Mars, Maroon 5, Miguel and Demi Lovato are among the chart-toppers slated to perform at KIIS-FM’s Wango Tango concert May 11.

The annual day-long fan jam at Carson’s Home Depot Center stuffs a who's who of current Top 40 (and a few buzzy emerging acts) onto one stage.  

Mars will open the festival, now in its 16th year, which will be hosted by pop purveyor Ryan Seacrest. The multi-hyphenate personality is expected to be joined by guest host Britney Spears. Spears is well-versed with the teen-attracting show, having performed at it twice.

Flo Rida, Will.i.am, Fall Out Boy, Afrojack, Icona Pop, Jason Derulo, Krewella, Emeli Sandé and Ariana Grande are also on the bill.

Tickets for Wango Tango go on sale to the public at 10 a.m. April 6, with a radio presale set for April 5.
