She has skyrocketed to fame following the international success of her single “In The Dark”… And, now Dev is set to perform at one of music’s biggest festivals.

The 22-year-old Portuguese & Mexican American electropop singer and songwriter—who recently hosted mtvU’s Woodie Awards—has signed on to perform at Lollapalooza this summer.

This year’s headliners are three of rock’s biggest names. Recently reunited Black Sabbath will end one of the nights while Red Hot Chili Peppers and The Black Keys will close out the others. Other acts include J. Cole, Florence + The Machine and The Shins.

Meanwhile, Los Jaivaswill perform at Lollapalooza as well. Hailing from Chile, the progressive-rock-andino group mixes rock with South American ancestral music.

And At The Drive-In, which was formed in El Paso, TX and plays post-hardcore alternative  music, will also be one of 120 acts taking the stage at the festival this you. Members of the band include lead singer Cedric Bixler-Zavala and guitarist Omar Rodríguez-López who when the band broke up formed the critically acclaimed  and successful Mars Volta group.

Lollapalooza, which takes place in Chicago, will run August 3-5, 2012.
