Mead, 22, was a contestant on Living series Dirty Dancing: The Time Of Your Life in 2008, where he performed among the finalists for judges Kelly Brook, Sean Cheesman, Miranda Garrison and Vivian Pressman.
He failed to win the series, but did go on to land a backing dancer role on a Take That tour afterwards.
On tonight's Got Talent show, Mead was shown talking about his decision to abandon a football career for dancing. The performer also claimed that it upset his father and brothers when he ditched the sport.
"He had high hopes for me to be a footballer," Mead told Ant & Dec. "He really wanted me to do something with it. There were arguments and discussion but I wanted to pursue dance.
"I don't speak to my brothers any more because I dance - which I think is stupid. But as the arguments grew and we grew, we got further and further apart."
Mead trained at graduate performance college Stella Mann before appearing on the Living show. In his profile for the dance series, he listed Rob Hoffman and Wade Robson as his heroes. He also confessed to having a phobia of tomato ketchup.
After being voted off The Time Of Your Life, he said: "It was a little bit heart-wrenching but I learnt more and more there every day. It has taught me a lot about me and I have got a more positive view of things."
Britain's Got Talent continues next Saturday at 8pm on ITV1.
