"If I'm too open about how I feel, then people wanna nag and pick and poke at me," he told Wenn. "I don't know Hilary either. She don't know me and I don't know her. I just need to shut up now about it. I think it's time... "
Though just last December, Hilary was still clearly on Aaron's mind, when he Instagrammed a picture of himself watching the holiday episode of Lizzie McGuire in which he guest-starred.
"'Merry Christmas, Lizzie McGuire.' #IWantCandy #AaronCarter #Flashback I never actually watched this before," he wrote before deleting the post.
Hilary and Aaron dated when they were just 13 years old. The 27-year-old "Oh Aaron" singer was famously caught in a love triangle in 2002 between the soon-to-be officially divorced star and Lindsay Lohan, whom he started dating after her.
"I don't know who she is today, she doesn't know who I am today but I would sweep her off her feet if I ever got a chance to again and fix what I did wrong," Aaron told ET last April about Hilary. "I'm going to do everything in my power to fix those relationships in my life just like I want to fix the relationship I had with the love of my life. I'm not gonna give up on Hilary ...ever."
