Christina Aguilera looks almost unrecognisable with her new dye job.

The 35-year-old pop princess has ditched her trademark blonde locks for a Jessica Rabbit-style fiery new look.

The Voice US coach unveiled her new style during her performance at a Hilary Clinton fundraiser in Los Angeles on Monday.

Christina, who has been no stranger to changing up her looks throughout her career, flaunted her striking new red hair as she put on a busty display onstage.

Other celebs performing at the event included the likes of John Legend, Stevie Wonder and Ricky Martin.

Meanwhile, Christina was reportedly “furious” at The Voice US bosses recently after she discovered that they had allegedly offering Blake Shelton and Gwen Stefani “huge bonuses” to flaunt their relationship.
