The former model said on today's Loose Women that she was surprised the picture caused such controversy when she posted it in March, saying she had simply seen it as a lovely moment.
But critics said it was unfair to Danielle's ex-husband Jamie O'Hara, the father of her three sons Archie, five, Harry, four, and George, two.
Danielle said today: "Do you know what? That was a really strange day for me. Because obviously for me that picture just represented how well [they get on]. When I actually took the picture, it was a warming moment for me like, 'Oh my gosh, that's amazing.' They were saying I was a disgrace for posting the picture because I should have thought about Jamie, my ex-partner. For me, that was a lovely picture. I don't care what people say, I'm happy."
As for Jamie, she said: "I don't know whether he has seen the picture. I haven't heard anything about it."
Danielle and Michael met at the gym and moved in together three months later. Nine months on, Michael proposed with a diamond ring he designed himself.
Flaunting the rock today, Danielle said: "He actually designed the ring and got somebody to make it himself. He has his own electrical company." She then joked: "He's probably still paying it off!"
"We met at the gym when he came over to me and told me I needed to squat better," she said. "He's got the banter as well. He's such a lovely guy so I am really lucky. I dated a few people after my marriage but I felt some were only ever interested in me, not my kids. They didn't want to know anything about them, but when I met Michael he wanted to do things with the kids."
Danielle and footballer Jamie divorced in 2014.
