How to not get nervous around conventionally attractive coworker

Not really my type but objectively handsome, LL Bean/Sears catalog looking guy at my workplace. Maybe it’s bc all other coworkers look pretty grisly, but I’m in meetings with him several times a week.

he’s sort of insufferable, says this one place isn’t his “fav brunch spot,” and is generally smug. if anything, he’s called me out several times during a meeting to correct me with a furrowed tucker Carlson expression and made me feel dumb.

anyway. Advice?
