We're not sure if Anne Hathaway ever truly planned a musical number with Hugh Jackman for 'The 83rd Annual Academy Awards' (Sun., 8:30PM on ABC), or if she just decided to give him grief about not doing one for no particular reason, but her impromptu song did set up James Franco's most memorable outfit of the night.

Hathaway sang her number in a very nicely tailored tuxedo, so Franco decided to continue the gender bending by coming out in a rather ill-fitting pink dress.

"Oh wow!" Hathaway said when Franco came out. Her reaction was so genuine we suspect this may have been a surprise for her as well. Or maybe ... acting!

"You got to wear a tuxedo, so I wore this," Franco explained. "The weird part is I just got a text message from Charlie Sheen."
