The couple – who have a three-year-old daughter Eliza - split up before when Adam assaulted Natalie in 2011. But the pair reunited after working on their relationship.
However, this time the relationship might really be ‘over’ according to a UK newspaper.
The claims come after Natalie, 30, was spotted without her engagement ring on during a day out to London Zoo with her daughter Eliza a couple of weeks ago.
And according to the paper, 33-year-old Adam has not been seen at their family home all week while Natalie has been tweeting about partying with her friends.
Natalie first got engaged to Adam in 2010 soon after they started dating, but split a year later after he was convicted of assaulting her.
Adam admitted in court that he had assaulted Natalie twice - once hitting her with a slipper and another time grabbing her, ripping her clothes and smashing up their flat – and was sentenced to 120 hours’ community service and given a restraining order.
But Natalie insisted she could move past the incident, saying: ‘I know it’s hard for some people to understand but we have worked at our relationship and I am so proud of how far we have come.’
‘I am so glad we gave it another shot because I love him.’
The pair proceeded to get engaged for a second time months later with Natalie revealing she had also been violent.
'Adam’s behaviour was unacceptable, but so was mine. I can see that now. I often lashed out physically at him when arguments weren’t going my way. I would hit him or slap him out of frustration and anger,’ she said.
Following the split, Natalie is said to be throwing herself back into work as prepares to return to her role as Sonia Fowler in EastEnders and rehearses for her upcoming panto appearance.
