Former BOYZONE star KEATING, who managed McFadden during his stint in Irish boyband Westlife, disapproves of sex outside of marriage and was famously a virgin until he wed YVONNE CONNELLY aged 21.
But the LOVE ME FOR A REASON singer has decided friendship comes first.
He says, "Brian is a good friend of mine.
"Delta's a sweetheart, she's a lovely lady. I hope they do another duet together and maybe an album.
"They're good together and they're very, very happy together and I wish them the best."
