"If I'm too open about how I feel, then people wanna nag and pick and poke at me," he recently 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... "
"I keep seeing that, that he keeps doing that," she said. "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 … Yeah, don't know each other … so … yeah."
Though whatever her response may be, Aaron does say that the "So Yesterday" singer will "always have a special place" in his heart.
"She's got a kid and she's married and I'm not trying to be that dude. That's not my intention," he says. "Hilary will always hold a very special place in my heart."
Hilary and Aaron dated when they were just 13 years old. Aaron was famously caught in a love triangle in 2002 between the Lizzie McGuire 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 in April about his ex, now 26. "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."
