International DJ and singer Havana Brown will join the southern hemisphere's largest car festival in January.
Ms Brown will join other festival acts such as Bliss n Eso, Illy and The Radiators at Summernats 28 in 2015.
Ms Brown is a platinum-selling recording artist who has sold more than 2.9 million singles worldwide and has toured with Lady Gaga, Pitbull, Britney, and The Black Eyed Peas.
Brown said she was looking forward to her upcoming show at Summernats.
"I love performing big outdoor festivals, and from what I've seen, the 'Nats is wild: crazy cars, passionate fans, and Bliss N Eso taking the stage after me. It's going to be a lot of fun," she said.
Aussie rock icons The Radiators will open the event on New Years Day, Havana Brown will perform on Friday night and 2013 ARIA award winner Illy will perform on centre stage Saturday night.
Summernats organisers said they had "served up an irresistible three nights of live music".
"Who would've thought… Havana Brown and Bliss n Eso on one night at the Summernats. We're stoked, Havana is a genuine Aussie international star and rounds out the great concert line-up for Summernats 28," organisers said.
"If that is not enough, imagine close to 2000 of Australia's most spectacular cars joining over 100,000 fans in a celebration of everything automotive."
