Aaron Carter, who briefly dated Lizzie McGuire Star Hillary Duff, has always been blatant about his feelings for his former flame.

He posted through social media, implying that he would always be there for Duff. However, when Duff recently filed for divorce from estranged husband Mike Comrie, Carter now wants his ex-sweetheart to leave him alone, according to E Online News.

"Some s-t I just don't get. Stop. Talking. About. It. I did," Carter wrote last March 6 through his Twitter account.

The twitter seemed to be a 'water off' Duff's back, as she tweeted yesterday with a positive vibe.

"Hey lil tweety birds. Ya brighten my day! Every last one of ya. Through thick and thin it seems that your all ways pullin for me," Duff wrote this statement through Twitter hours after Carter made his tweet.

Last year, when Duff was still on temporary separation with Mike Comrie, she shared what she felt about her ex-boyfriend's tweet through an interview with Buzzfeed. She admitted feeling a little 'creeped out' that Carter was still not over her.

"I keep seeing that he keeps on doing that. 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," says Duff.

"Don't be that stupid d--- that loses the love of your life forever. Like me, I'll spend the rest of my life trying to better myself to get back to her. I don't care what any of you think," says Carter in a previous tweet last 2014.

When Carter was asked by a fan, whether this post referred to Duff, he immediately replied, "Sure am,"

Meanwhile, Duff recently filed for divorce last month from Comrie, citing irreconcilable differences.
