Will Zac Efron, Miley Cyrus And Robert Pattinson Boost Oscar Ratings?

The 'High School Musical' and 'Twilight' stars are rumored to be appearing at Sunday's Academy Awards.

With rumors flying that young stars like [movieperson id="438080"]Zac Efron[/movieperson], [movieperson id="441942"]Miley Cyrus[/movieperson] and [movieperson id="365131"]Robert Pattinson[/movieperson] are going to make appearances in one form or another at Sunday's Academy Awards, it seems that producers are attempting to recover from last year's all-time low ratings, perhaps with a little stunt casting.

Efron is rumored to be presenting Best Original Song and hitting the stage with his "High School Musical" co-star and real-life girlfriend, [movieperson id="318323"]Vanessa Hudgens[/movieperson], E! Online reports. Sources told the site that the Disney stars will join [movieperson id="454680"]Beyoncé[/movieperson] and host [movieperson id="234610"]Hugh Jackman[/movieperson] onstage for a musical number directed by "Australia" helmer Baz Luhrman. "Mamma Mia!" stars [movieperson id="346182"]Amanda Seyfried[/movieperson] and [movieperson id="267747"]Dominic Cooper[/movieperson] are also rumored to be participating in the number if their scheduling conflicts are resolved.

The show's producers have said that for this year's broadcast they want to shake things up, so lining up a roster of young megastars may be just the formula to do that. Rumors began surfacing on Monday that "Twilight" heartthrob Robert Pattinson will present an award. No word yet on what he'll be presenting or if Kristen Stewart will be by his side.

Of course, we can't forget the presence of the teen queen herself, Miley Cyrus. While Hannah Montana isn't yet scheduled to take the stage to perform or present, E! reports that she will be present in support of [movie id="330763"]"Bolt,"[/movie] which is up for Best Animated Feature.

Reps from the Academy Awards had not responded for comment on the rumored lineup by press time.
