Sean Penn Reveals His Obsession With 'The Bachelor'

— -- Sean Penn and Charlize Theron seem very much in love.

However, they do argue over one very important issue: whether to fast forward through the slower parts of "The Bachelor."

"I don't really want to hear the conversations. I want to know the decisions. Is he gonna decide on this one or this one?" Penn said during an appearance on "Jimmy Kimmel Live." "And I wanna see somebody cry, and then see somebody get ecstatic and then see them cry."

Penn, 54, is promoting his film, "The Gunman," but in his spare time, he's been keeping up with the ABC dating reality series. He also expressed his opinion on how the next season of "The Bachelorette" should go.

"It's gonna have to be Kaitlyn," he said, though Kimmel refused to choose a side.

"I still can't believe they got Matthew McConaughey to be the bachelor and call himself something different," he added.
