Jordis Losana Sikahema Unga (born August 6, 1982) is an American rock singer from Forest Lake, Minnesota.

After years of building a cult following in Minneapolis, as a vocalist for The Fighting Tongs and Liars Club, Unga reached international fame for her performances on the first season of the CBS television reality show Rock Star: INXS where 15 contestants competed to become the lead vocalist for the Australian rock band INXS.

Ex-members including Unga, drummer Corey Frazee, guitarist "Moose" Hitchcock and bassist Josh Hoglund formed "Liars Club".

Halfway through the competition, Unga was invited by Navarro to perform The Clash's "Should I Stay or Should I Go" with his band Camp Freddy at the West Hollywood House of Blues.

Camp Freddy featured former The Cult bassist Billy Morrison on guitar and ex-Jane's Addiction drummer Stephen Perkins.

Epic Records paired her with various collaborators, including David Hodges and the duo Anne Preven and Scott Cutler of Ednaswap.

Unga's first official live performance was October 15, 2005, singing the national anthem at Staples Center in Los Angeles, California for the boxing event 'The Rematch; Mora vs. Manfredo Jr.' Unga was invited by Yolanda 'Lonnie' and Muhammad Ali to perform at the Grand Opening for the Muhammad Ali Center located in Louisville, Kentucky on November 19, 2005.

As a part of the ceremonies, Unga shared the stage with James Taylor, Richie Havens, Hootie and the Blowfish, Jim Carrey, Chris Tucker and Herbie Hancock.

Unga has co-written music with Oscar-nominated songwriters Anne Preven and Scott Cutler, Grammy winning artist and producer David Hodges, and Kevin Griffin (lead singer of Better than Ezra).
