David Letterman still doesn't care what you think about his new look following his retirement, as proven by his latest outing while on vacation in St. Barts.

The former Late Night host was spotted getting in a little workout during his Caribbean trip this week, but we almost didn't know it was him!

Rocking a new bald head as he continues growing out his beard, Letterman is nearly unrecognizable with the exception of that genuine grin we came to know and love during his 33-year stint on The Late Night.
