Chris Pratt, Jennifer Aniston to present at Oscars

A slate of new stars have been added to the roster for the 87th Academy Awards.

Among those set to take the stage as presenters: Jennifer Aniston, Sienna Miller, David Oyelowo, Chris Pratt and John Travolta, show producers announced Tuesday.

Aniston starred in the 2014 film "Cake", while Pratt starred in summer blockbuster "Guardians of the Galaxy." Miller co-starred in "American Sniper" and "Foxcatcher," both of which have garnered multiple Oscar nominations this year. And Oyelowo portrayed Martin Luther King, Jr. in this year's best picture nominee "Selma."

They join previously announced presenters Cate Blanchett, Matthew McConaughey, Lupita Nyong'o and Jared Leto -- who all won acting Oscars at last year's awards.

The list of performers at the ceremony now also includes Jennifer Hudson, who producers announced Tuesday will grace the Oscars stage this year.

"We're creating several musical sequences for the Oscars and we couldn't be happier that our friend, Jennifer Hudson, will be performing in one of them," says Craig Zadan and Neil Meron.

The 2015 Oscars -- hosted by Neil Patrick Harris -- will air live Sunday, Feb. 22, starting at 7 p.m. ET on ABC.
