The two solo acts, who have the made the show's Final 24 judges' houses round, became the subject of a DS forum thread after they began sending each other messages on Twitter.
"Lloyd has very bad morning breath, but God what a sight to wake up to... (on a completely different note, he is the best spooner I know)," wrote Boroian. He added later: "Yes, I know, I really do have to stop touching Lloyd's face."
Forum user Madlh100 said: "Does anyone think there's anything between Ethan and Lloyd? It was bought to attention in the X Factor boot camp forum tonight."
Richieosborne89 added: "Ethan could be gay. But Lloyd I highly doubt. They are probably just mucking about. Would be so funny/cute if it were true though!"
Responding to the forum speculation, Boroian said: "Hi guys! Just to clear the air, Lloyd and I do share a certain bromance, but we are both straight... Jokes about the forums!"
The X Factor continues at 8pm on Saturday on ITV1.
