Walt Disney Pictures CEO Bob Iger confirmed the news, reported Ace Showbiz.
"Joss Whedon has signed an exclusive deal with Marvel Studios for film and television through the end of June 2015," Iger said.
"As part of that deal, Whedon will write and direct Marvel's The Avengers 2 as well as help develop a new live action series for Marvel Television at ABC. He will also contribute creatively to the next phase of Marvel's cinematic universe," he added.
Previously, Whedon sparked frenzy as he hinted that he might not return to "The Avengers" sequel.
"I have not come to a decision on directing 'Avengers 2' yet. I am having too much fun with this 'Firefly' reunion now," Whedon had said.
With Whedon serving behind the lens, "The Avengers" has successfully earned around USD 1.5 billion worldwide. The massive gross made the superhero ensemble the third-highest-grossing flick of all time after James Cameron's "Avatar" and "Titanic".
Before moving on to "The Avengers 2", Disney and Marvel will have to work on a number of highly-anticipated sequels, including "Iron Man 3", "Thor: The Dark World" and "Captain America: The Winter Soldier".
