Hilary Duff still really cares about MIKE COMRIE.

The 'Chasing the Sun' singer, who announced she had amicably separated from the former professional ice hockey player in January after three years of marriage, says they haven't filed for divorce because they are still working on their relationship.

The 26-year-old star, who has son Luca, two, with Mike, told KIIS 106.5's 'The Kyle & Jackie O Show' in Australia: ''We've uncoupled, for now. I mean, if there wasn't a chance for getting back [together], I think we would've filed for divorce. We're not putting any... I talk about this so much, I really don't want to talk about it anymore. But we are like... I just talked to him this morning! We really care a lot about each other.''

But the blonde beauty insists doesn't get upset by all the speculation about their marriage.

She said: ''In my experience, there's truth to what's written. Usually, I find there's truth to a lot of the stuff somewhere.''

Meanwhile, the former Disney star admits she was shocked that her ex-boyfriend Aaron Carter declared his love for her on Twitter in March.

Asked about the 'Crush On You' singer, whom she dated when she was just 13, Hilary told BuzzFeed: ''I don't know how I feel. I mean, that was so long ago, and obviously I'm still married, and I have a baby and we kind of just... don't know each other. So, yeah...''
