Four former Best Actress winners will converge on stage at this year's Oscar telecast, the show's producers said Wednesday.

Halle Berry, Sandra Bullock, Nicole Kidman and Reese Witherspoon will present an award, although the show's producers were mum about whether or not they will take the stage together. If they do, it may mean a return to a format that was deployed and favorably received during the 2009 broadcast.

During that show, former winners of acting awards appeared on stage together to give short speeches praising each of the nominees. That was revived in a slightly modified form in the 2010 telecast, in which co-stars or celebrity friends of the various nominees were called on to pay tribute before the winner was announced.

Traditionally, the previous winner of an acting award reads out the nominees and hands out the statue without assistance.

Berry won the Oscar for her performance as a grieving widow in "Monster's Ball" (2001), Bullock for her work as a feisty housewife and football fan in "The Blind Side" (2009), Kidman for playing a depressive Virginia Woolf in "The Hours" (2002) and Witherspoon for channeling June Carter Cash in "Walk the Line" (2005).
