Chloe is AJ's dance partner but I have never seen any reference to her being his girlfriend. Like a pp said, I would be amazed if girls were his type 
The media and Shirley are definitely trying to 'ship' AJ and Molly. Presumably because they need a romance storyline and they are both (presumably) single but it's just not there is it?
Gemma is single but they can't do anything with Alijaz but allegedly she is seeing Gorka lucky cow but hard to do it when they aren't dance partners 
Agree that Joe Varney has shown a completely different side this year. Not smarmy Italian stallion but hot, caring hunk
