The 56-year-old entertainer didn't hesitate to confront Delta about persistent rumous she is dating Seal.
Appearing on the Kyle and Jackie O Show on Wednesday morning, Boy George admitted he isn't full convinced the pair haven't been enjoying a romance, despite Delta telling him they're not involved.
After confirming he was coming back for the new season of The Voice, George said he was 'disappointed' Seal wouldn't be returning.
'We got there in the end, we were a great tag team,' he said of the twos chemisty. 'Do you think becuase of him tag-teaming you and tag-teaming Delta, he thought I'll give it a miss for a year?' asked shock-jock Kyle, implying the affair between Seal and Delta.
He revealed he had called Delta via FaceTime after the show finished taping to see 'if she was going out with Seal.
'I was reading all this stuff [about them] and thought, I must be the worst judge of character! I was like, 'maybe she's living with him in LA, so I rang her up,' he started.
'I said, 'Delta, are you going out with Seal?' She was like, 'No, I'm not!' and I obviously believed her because, she was really convincing.'
Kyle interjected, 'What I would have done is made her walk through the house into each room to prove Seal wasn't there.'
I don't know if you know, but I'm sure I saw that boy who was in her team dart across the background. That Tim bloke!' said George, referring to contestant Tim Conlon.
'She's dating one of the contestants!' Kyle replied, shocked.
'I'm pretty sure,' joked George.
