Former West Life singer and now judge of “Australia’s Got Talent” Brian McFadden has claimed that ex-fiancee, Delta Goodrem told him about going out with Nick Jonas before the world saw her leaving a Los Angeles theater holding hands with the Disney star.

And McFadden insisted that “he is happy if Delta is happy”.

"She told me about it beforehand, whatever makes her happy,” McFadden was quoted as saying by Ninemsn.

He added, describing the photo taken of the rumored celebrity couple: "It was positive. She looks happy, if she's happy I don't mind."

The 32-year-old Irish singer-songwriter may sound okay about ex-fiancee’s newfound love, but the singer issued a warning against Nick Jonas and other men setting their eyes on the Aussie songstress.

McFadden said: “But there's a warning from me, if anyone hurts her they're dead."

The “Real To Me” hitmaker also clarified earlier reports that he was dumped by Goodrem, whom he had had a relationship for seven years before they split in April.

As noted by Ninemsn, McFadden maintained that neither his party lifestyle nor long distance relationship killed their long-term relationship that even cut their earlier plans to walk the isle and said,"we just knew we'd grown apart".

Emphasizing that the former celebrity couple still keep in touch even after their break-up last month, McFadden said that they are ‘still really good friends’.

"I think we've taken a mature approach to what we've done, we talked about it and decided to move on in our separate ways,” said McFadden.

"We can still be there for each other but start the rest of our lives now. I genuinely love her to bits. She's a good person and she's given me seven of the best years of my life. I'll always be there for her."
