J Law, who is herself nominated for a Best Supporting Actress award, will no doubt have a witty speech prepared for her whomever she is presenting a statue to.
As the face of Miss Dior, the 23-year-old actress will likely wear a dress by the label's designer, Raf Simons, on the evening – and we can't wait to see what it looks like.
Brad Pitt and Angelina Jolie will also take to the stage, but whether or not we'll see a repeat performance of their matching Bafta tuxedos remains to be seen.
And homegrown talent Emma Watson is another of our favourite faces that we will get to see, too. We're hoping the Bling Ring star gets to take her new Ruby player boyf to the ceremony, as we'd love to see those two together on the red carpet.
The full list of stars who will help with the evening proceedings was announced by Oscar producers Craig Zadan and Neil Moron yesterday.
We are very excited that the Hollywood community will be turning out in force for Sunday's Oscar ceremony," said Zadan and Meron in a statement. "We sought to include a tremendous diversity of stars to represent not only this year's nominees, but the legacy of the motion picture business as well.
The full list includes:
Robert De Niro
Samuel L. Jackson
Michael B. Jordan
