Jonas, who also denied rumours he is gay, told Details magazine that his relationship with Greene 'feels good' - although by the time the mag hit the shelves the couple had confirmed their split.
'I think what works about it is she really puts my feelings first. She understands my busy schedule,' he told Details. 'She'll fly out to my shows — she's been to places in South America that I can't even pronounce.'
He even revealed he has a great relationship with Greene's father: 'Her dad can drink me to shame. He's awesome.'
Jonas raised the gay rumours himself, by joking when asked who would break up with him that it would be 'some guy'.
However, he stressed: “There's nothing wrong with being gay. But I'm not.”
