Who is AJ Pritchard?

AJ, 21, comes from a dancing family. His parents run a dance school in Cheshire. He started dancing competitively at the age of 12 and it was at his parents’ dance school that he met his professional dance partner – fellow Strictly pro Chloe Hewitt.

As well as competing at the highest level – winning the National Youth Latin Championships for three years in a row, as well as the British Open Youth Latin Championships and the European Youth Latin Championships – AJ and Chloe also appeared on Britain’s Got Talent. In 2013 they made it through to the semi-finals of the ITV talent show.

“The two shows are completely different in that when I did Britain’s Got Talent it was very much a quick-fire thing,” AJ told What’s On TV.

“We went there, we auditioned, then we did the live show on the night. Whereas with Strictly, it really is like being part of a family.

“We see each other every week – the pros, the celebrities, all the staff – we know each other so well and, every week, we get to know each other even better.”
