Former Westlife member Brian McFadden said that he will not sue The Voice coach and former fiancee Delta Goodrem.

Despite McFadden's sour-graping when Goodrem did multiple interviews making comments about their relationship, the singer decided to put everything at rest.

"Do I wish that it ended earlier? Yes. Do I wish I had the courage to leave earlier? Yes, I do. I think what we came to is that we were very different people - extremely different people," Goodrem said to Karl Stefanovic on "60 Minutes" on Sunday.

The singer also revealed minute details about the break-up in the latest issue of Vogue Australia wherein she said that she was unhappy during the course of their relationship.

In her own words, Goodrem said: "There is so much I'd like to say. I was really unhappy and I didn't know how to get out. I learned. I got there in the end. I feel like it's a totally different chapter; I feel like I'm back to being me again."

McFadden was said to be considering his legal options but discarded the idea later. Instead, the former member of the Westlife tweeted: "I'm not considering legal action. I also wouldn't stoop as low as her. If I did, it would change everything. But I'm happy!"

Brian posted a string of tweets before that appear to be an attack on his ex and her statements about their relationship in Vogue Australia.

On his first tweet, he wrote, "Sometimes silence is golden. People love to try and deflect attention from their own downfalls onto others."

It was followed by another tweet saying, "And for the record. I've seen it all before!!" It is assumed that this tweet refers to his ex-wife and mother of his two children Kerry Katona, who he once called a "pig-faced mole."

Brian also posted a praise to his current fiancée, Irish model and DJ Vogue Williams, "Randomly want to thank @VogueWilliams for making me the happiest man on the planet."

Brian said that he and Delta parted ways amicably and they remained friends after they have broken up. Apparently, that is not the case. Delta has not released a statement yet.

It is more than a year since the high profile seven-year relationship of Delta and Brian ended. For months, she was tight-lipped about the cause of her break-up when her engagement with McFadden was called of. Goodrem found new love in the arms of Disney star Nick Jonas only to part ways earlier this year.

There are no further comments from both parties.
