For the first time since hosting the Oscars, James Franco is addressing rumors that he was stoned during the gig. In an interview on 'The Late Show With Dave Letterman,' airing Thursday evening, the actor reveals why he appeared so low energy.

"People said I was under the influence," Franco said during his 'Late Show' interview, which airs tonight.

"Now why would they say that?" asked Letterman with a laugh.

The '127 Hours' actor replied, "I've thought about it. I think I know why, because--I love her--but Anne Hathaway is so energetic, I think the Tasmanian Devil would look stoned standing next to Anne Hathaway."

"Truthfully," Franco added, "and I haven't watched it back, maybe I had low energy. I actually played those lines as well as well as I could."
