Way back in 2000, Aaron Carter started dating Hilary Duff.
He then cheated on her with Lindsay Lohan... got back together with the actress... and has admitted to cheating on her again with her best friend!
But now Duff is divorced from Mike Comrie and Carter is making his play to win her back.
"Don't be that stupid douche that loses the love of your life forever. Like me," Carter Tweeted yesterday, admitting he was referring to Duff and adding:
"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."
Wow. How sweet. How unexpected. How surprisingly honest.
And what did Duff say in return?
Nothing. She Tweeted a photo of clothes on the floor Thursday and included with it a caption that read "Closet clean out."
Still, Carter remains undeterred! You've gotta admire and smile at his response to Duff's image:
Come on, Hilary! Can't a guy make a mistake?!? Twice? Cuff 4 eva!
