The Made In Chelsea favourite appeared alongside Larry Lamb on today's Loose Women & Men, and won over viewers with his candid chat on topics including whether kids should be shown porn in school as a form of sex ed, and making his parents proud.
It was a different side to Spencer for many people, who only know him for his ladies' man antics in MIC or his brief stint in I'm A Celebrity... Get Me Out Of Here!
He spoke eloquently on a variety of topics including an emotional discussion where he opened up about his late brother, Michael, who died in 1999 while climbing Mount Everest. "When you feel like giving up, you think about him and how he wouldn't have given up. He was such a brave young man. Often you find the strength to continue with something by thinking about him."
There was also a nod to his I'm A Celebrity roots, with a story about the sales of edible insects being on the rise. "I'm back in the jungle," quipped Spencer.
He also dropped MIC co-star Jamie Laing in it during a discussion on men wearing make-up. While Spencer wouldn't wear it regularly, he said: "Jamie Laing wears loads of make-up, as you can probably see. He typically does indulge in a bit."
Ooh, wonder what Jamie will say to that?
During the show, plenty of people took to Twitter to praise Spencer on his appearance, saying they'd really enjoyed watching him and pleading with him to become a regular panelist.
