Teen girls have two new reasons to tune in to the 68th annual Golden Globes this Sunday. Today Justin Bieber and Zac Efron were both announced as presenters.

In addition to this duo and the iconic hairstyles they'll bring to the stage, MTV reports that another teen-pleaser was added to the presentation lineup. Actress Olivia Wilde, notably popular for her role in 'Tron,' will be handing out an award as well.

Non-tweens, too, will find some of their Hollywood favorites doling out trophies. 'Spider Man's' Andrew Garfield, Steve Carrell, Robert Downey Jr., Sandra Bullock and Kevin Spacey are all confirmed presenters. Robert De Niro will be honored with a lifetime achievement award presented to him by 'True Grit' star Matt Damon.
