Jeff Bridges has been added to the list of presenters for the Screen Actors Guild (SAG) Awards.

The 'Tron: Legacy' actor and '30 Rock' star Alec Baldwin will be among the long line of presenters at the prestigious ceremony on January 30, with LL Cool J, Josh Duhamel and 'Glee' hunk Corey Monteith also involved.

Jeff won the Outstanding Performance by a Male Actor SAG Award last year for his role as a drunken singer in 'Crazy Heart', and is this year nominated in the same category for his performance in 'True Grit'.

Other previously announced presenters include Betty White - who celebrated her 89th birthday earlier this week - Rosario Dawson, Hilary Swank and Eva Longoria.

The awards - in their 17th year - celebrate performances in both film and television, with 'The King's Speech' and 'Black Swan' leading this year's nominations with four apiece.

Other films to do well include comedy drama 'The Kids Are All Right', starring Annette Benning and Julianne Moore and boxing drama 'The Fighter'.

The awards take place at the Los Angeles Shrine Exposition Centre.
