Eton-educated Spencer has earned the reputation of being a bit of a ladies' man and a die-hard party fan. He last dated Stephanie Pratt on the show, who had flown over from America just to be with him.
The couple soon split after it emerged that Spencer went back to his old cheating ways — the same reason why Lucy and Louise also broke up with him.
Spencer and Louise, who first started dating on-off when they were 18, could be getting back together in the next series.
"Louise and Spencer have been on and off for six or seven years," fellow cast member Jamie has said in the past, hinting at a possible reunion. "I still think there's something there."
