Pop star Hilary Duff has opened up about the state of her relationship with estranged husband MIKE COMRIE, insisting she has no interest in ex-flame Aaron Carter's love protestations - because she's still determined to fix her marriage.

The So Yesterday singer and sportsman Comrie separated earlier this year (14), and the news prompted Carter to offer his ex-girlfriend a shoulder to cry on, professing his undying love for Duff.

But she's not interested in rekindling her past romance with the former teen pin-up because she's not ready to call time on her marriage.

In a revealing new radio interview in Australia, she tells Kiis 106.5, "We've uncoupled, for now. I mean, if there wasn't a chance for getting back, I think we would've filed for divorce.

"I just talked to him this morning! We really care a lot about each other."

And, as for a Carter reunion, the singer insists that's not something she's planning, telling BuzzFeed.com, "I don't know how I feel (about that). 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."
