Robert Rinder rocked the red carpet just hours being taken to hospital for urgent surgery.
The telly judge, 44, told fans he'd suffered a prolapsed disc in his back as he shared a snap from his ward on Monday.
The criminal barrister dashed to hospital after presenting Good Morning Britain, but he looked the picture of health as he posed for the photos at The Reluctant Traveler premiere on Tuesday.
Larking around with comedian Alan Carr, 46, Robert cut a dapper figure wearing a tailored black shirt and trousers.
In one snap he kissed the Chatty Man star on the cheek as the pair looked happy to be in each other's company.
In another, Alan returned the favour as the duo made their way inside the Everyman cinema in London.
The photos came just hours after Robert told his followers "life can change in a moment" after suffering the painful injury.
Sitting in his hospital bed, wearing a surgical gown, he said: "Started the day holding politicians to account on GMB and interviewing Lulu & Richie Sambora.
"Finished it having a prolapsed disc in my back repaired and healed.
"‘Life can change in a moment.. Hold on to joy wherever you find it (thanks brilliant medical team)."
A prolapsed disc, also known as a slipped disc, can cause severe pain as the soft tissue between the bones gets pushed out of place, pressing on the nerves.
After revealing his injury, fans rushed to send Robert their well wishes, with one saying: "OMG a prolapsed disc is so painful, I'm very glad you've got it repaired and are on the mend."
The star's fan also rushed to Rob's support when he paid an emotional tribute to his late dog Rocco on GMB after his "sudden" and "unexpected" death in December.
The barrister was left heartbroken after his beloved pooch passed away and choked up as he spoke out about his loss.
The Judge Rinder star told Susanna Reid: "He was a friend of yours, like all dogs he could see the soul of somebody even where they may express their undivided indifference to them."
Offering her support, Susanna said: "I know how close you were to Rocco," as her pal admitted the loss of his pet had left him feeling "lonely".
Robert went on: "It's not just people, it's about needing to have an emotional connection and feeling a sense of mission and purpose, and people and kids and family bring that. For a lot of people it's a pet and in my case, it was the structure of my day.
"Like most people I wasn't necessarily a dog person, but then this beautiful snoring creature came into my life and gave me absolute loyalty and unconditional love."
