Singer Aaron Carter has set his sights on winning back his teenage sweetheart Hilary Duff following her marriage split from former ice hockey player Mike Comrie. Carter dated the Cheaper By The Dozen actress/singer in the early 2000s, but they split amid rumours he had become embroiled in a love triangle with fellow child star Lindsay Lohan. The pop star has regretted his actions ever since and has continued to profess his desire to reunite with Duff, and now she is separated from Comrie, he is hoping to give their relationship another go. Carter, 26, took to his Twitter.com account on Wednesday (05Mar14) and re-tweeted a fan's photo of Duff, which featured the caption, "hilary duff is flawless". He then followed up the post by writing, "Don't be that stupid d**che 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." Asked by a follower if he was referring to Duff, he simply replied, "sure am". Carter's confession comes two months after Duff announced her separation from Comrie, the father of her son Luca, who turns three later this month (Mar14).
