Whatever had tickled their funnybones, it was clear Anne Hathaway and Denzel Washington share the same sense of humour.
The pair got the giggles during the Nobel Peace Prize ceremony on Friday.
Being on the same wavelength bodes well for their joint appointment on Saturday - hosting the Nobel Peace Prize concert.
The special gig will feature performances from Florence and the Machine, India.Arie, Elvis Costello, Robyn, Jamiroquai, and Barry Manilow.
It honours Nobel Peace recipient Liu Xiaobo, the dissident writer and human rights activist who couldn't pick up his award in person and who won't make the party.
He's currently one year into an 11-year prison sentence in China for "inciting subversion" after calling for democracy and human rights.
