David Letterman was photographed while vacationing in St. Barts looking totally different.

He was caught taking a jog, sporting yellow shorts, a scruffy beard and a totally bald head. Letterman is looking much different than he looked when he entertained Americans for 33 years as the host of “The Late Show.”

Daily Mail Celebrity tweeted the images of Letterman to its 186,000 followers. Check them out here.

CNN reported that Letterman has kept a "low profile" since handing his show over to Stephen Colbert.

Letterman’s new look has sparked a conversation on Twitter, comparing him to Jolly Ol’ Saint Nicholas.

Freddie Campion, the engagement editor for GQ, tweeted, “David Letterman accidentally killed Santa and is now slowly morphing into him like Tim Allen in 'The Santa Clause.'”
