The couple, who began dating last year, are now at the centre of new split reports.
Lauren posted an intimate photo of the pair this morning (9 September), but a spokesperson for Spencer has confirmed to Reveal that he is "currently single".
We have reached out to Lauren's rep for comment.
Lothario Spencer revealed he was officially off the market during the eighth series of MIC.
Introducing Lauren to his mates after she spent time meeting his family, Spencer seemed smitten as he welcomed the occupational therapist from Hertfordshire to his group of friends.
It was a rocky ride for the couple, as Spencer's exes went out of their way to warn Lauren about his previous cheating ways. But, Spencer said he was a changed man, and after realising it was time to "grow up", he inhabited a healthier and sober lifestyle.
In April, Spencer told Reveal about his relationship with Lauren: "We're loved up. I mean, it's getting to be one of the longest relationships I've ever had and I feel in a really good place still.
"I have to say, in the past I haven't been one for relationships, but this is good, we really enjoy each others company and it's going very smoothly. Plus there's minimised arguing."
However, the pair have faced hurdles in their relationship. In the last series of the E4 reality show, Lauren was devastated after Spencer revealed he kissed another girl during a night out with the boys.
She eventually took him back after Spencer persuaded her to give him another chance. The pair seemed loved-up in recent snaps over the summer, and more recently, Spencer was gushing over Lauren on his birthday last month.
