Stephen Colbert and his wife of 31 years, Evelyn McGee-Colbert, made a rare public appearance together Saturday night at the Kennedy Center Honors gala in Washington, D.C. — and the internet hasn’t stopped talking since.

The 61-year-old Late Show host, usually known for oversized suits and nerd-chic glasses, looked like he’d just stepped off a movie set: tailored midnight-blue tuxedo, crisp white shirt unbuttoned just enough, fresh fade haircut, trimmed beard, and a relaxed, almost mischievous grin that photographers say they’ve never seen before.

But the real show-stopper? Evelyn, 58, who has spent three decades deliberately avoiding the spotlight, looked breathtaking in a floor-length emerald gown, diamond drop earrings, and her signature dark hair swept into an elegant chignon. The couple — married since 1993 and parents to three grown children — were glued together all night: holding hands, whispering, laughing like newlyweds.

“He kept looking at her like she was the only person in the room,” one attendee told The Post. “I’ve been on that red carpet for 20 years and I’ve never seen Stephen like this. He’s glowing.”

Social media exploded within minutes.

“Stephen Colbert just aged backwards 15 years???” one X user posted alongside side-by-side photos. “And Evelyn looks like she could be on Succession. Who allowed this level of hotness?”

Another wrote: “That man is going through something and whatever it is, I need the regimen.”

Sources close to the couple say the transformation began quietly over the summer. After Colbert announced The Late Show would end its run in May 2026, friends say he finally had “breathing room” for the first time in a decade.

“He dropped 25 pounds, started working out with a trainer five days a week, got Invisalign, laser skin treatments — the full midlife renaissance,” a CBS insider dished. “But the biggest change? He’s happy. Like, genuinely happy. The stress of the show was killing him.”

Evelyn, an actress who famously played his on-screen wife in Strangers with Candy and largely stepped away from public life to raise their kids in suburban New Jersey, has apparently been the mastermind behind the glow-up.

“Evie told him, ‘If this chapter is ending, we’re doing the next one looking like we never left the honeymoon,’” a family friend revealed. “She booked the stylist, the dermatologist, even picked the tux. She wanted the world to see the man she fell in love with at 23.”

The couple met in 1990 at the Spoleto Festival in Charleston, South Carolina. Colbert has famously recounted the “thunderbolt” moment: spotting Evelyn across a crowded lobby and telling his mother that night, “I’m going to marry that girl.”

Saturday night felt like a throwback to that story.

When a reporter on the carpet asked what brought them out together after so many years apart at events, Colbert flashed that new megawatt smile and said simply: “We’re celebrating being us again. Finally.”

Evelyn, squeezing his hand, added softly: “He’s always been this handsome. The world’s just getting to see it now.”

The Kennedy Center Honors — where Colbert was there to support honoree Francis Ford Coppola — suddenly became the Colbert show. George Clooney reportedly joked, “Stephen, save some hot for the rest of us.”

Even Jon Batiste, performing later that night, dedicated a song to “my glowing brother Stephen and the queen who keeps him shining.”

Fans are now flooding Evelyn’s rarely-used Instagram (which has exactly 12 posts in eight years) with heart emojis and pleas for couple photos.

One viral comment summed it up: “Evelyn McGee-Colbert just ended every other Hollywood marriage. 31 years and they look THIS in love? Goals don’t even cover it.”

As for what’s next, sources say the couple is planning an extended European sabbatical after the show wraps — “just the two of them, no schedule, no cameras.”

Whatever they’re doing, it’s clearly working.

Stephen Colbert isn’t just exiting late-night — he’s walking out looking better than he ever has, with the woman who’s been by his side the entire time finally getting her well-deserved moment in the light.

And America can’t stop staring.
