Stephen Colbert Sports Sleeveless Suit Jacket, Bares Abs for His Sexiest Photo Shoot Ever

Stephen Colbert really wants to be the sexiest man in late night.

The Late Show host -- who took over the CBS program in 2015 after David Letterman retired -- struck a series of seductive poses for the August issue of InStyle magazine -- and his modeling skills are quite impressive.

In one image, Colbert is wearing a dapper navy blue Tommy Hilfiger suit with the slacks cut into shorts and the jacket's sleeves ripped off. The 53-year-old comedian also bares his six-pack abs -- or someone's abs -- while posing in a T-shirt with a muscular stomach printed on it.

Colbert's humor came out during the photo shoot, but he got quite serious when talking to the magazine about the struggles he faced before fame. "In my late 20s, early 30s, I had a nervous breakdown," he says. "I was subject to panic attacks and stuff like that except when I was onstage. I would curl up in a ball on a couch backstage, and then I'd hear my cue coming up, and I would uncurl, go onstage, do the show, and then go offstage and curl up again."

Next up from the September issue! @StephenAtHome finds joy (and sanity) while poking fun at politics. “I care about the news, I care about what’s happening, and I love jokes, so to be able to say to the audience, ‘Come over here, and we’ll hopefully explain it to you in a different way and make you laugh about it’—that is an absolute joy.” Click link in bio for @LauraBrown99's full story.

A fun Stephen Colbert fact? “Dumb” is one of his highest forms of praise. In the @ColbertLateShow writers room, “Someone will come up with an idea, and it’s just dumb enough,” he tells @LauraBrown99. “It’s a compliment. It takes a lot of mental provender to come up with something truly dumb, which is why I think Donald Trump must be a genius.” I Photograph by @MillerMobley

Abs put on with scotch tape? That is pretty dumb.

“I think I’ve gained 15 pounds since Donald Trump became president,” jokes Stephen Colbert in our September issue. But that didn't stop @StephenAtHome from showing off his um, "abs" on set. Swipe for more BTS from the shoot.

Then, he says, something changed. "I went to write a new show, I guess it opened a door in my brain, and it was over," Colbert recalls. "I woke up one morning, and it didn't feel like my skin was on fire. But then I thought, 'Well, I can't ever stop doing this because that skin-on-fire is always right behind the door.'"

Now Colbert is leading in the late night ratings, and after this photo shoot, it's clear he has both brains and beauty.

The late-show host isn't the only funnyman turning heads this summer. Steve Carell -- who was once a correspondent with Colbert on The Daily Show -- also garnered some attention for his silver fox style while promoting Despicable Me 3 in June. "I am so sick of people just looking at me for my physical attributes," he quipped to ET when asked about his handsomeness. "It's just genetic. There's nothing I can do."
