The 'Argo' star thinks the 'Magic Mike' actor is a worthy recipient of People magazine's Sexiest Man Alive title this year - an honour he was awarded in 2002 - because he is a very attractive guy.
Ben told 'Access Hollywood': "I think [Channing] is deserving, and always has been.
"He's a very good guy and an extremely, extremely sexy man.
"I mean, what else can you say? Have you seen 'Magic Mike'? I think that said it all!"
Along with Channing, Ben has also been named one of GQ magazine's Men of the Year and the 40-year-old star - who has children Violet, six, Seraphina, three, and nine-month-old Samuel with wife Jennifer Garner - admits the cover picture of him to commemorate the honour is one of the few he is happy with.
Discussing the US magazine's cover, he said: "I never really like pictures of myself. But, you know, at least it's not horribly embarrassing, which is what I'm always worried about."
With Channing named GQ's Movie Star of the Year and Ben named Filmmaker of the Year, other, other previously-announced recipients of the honours include Rihanna, who is Obsession of the Year.
