Did Aaron Carter Just Call Out Hilary Duff on Twitter?

Looks like Aaron Carter is no longer as enamored with his ex-girlfriend Hilary Duff as he once was.

In fact, judging by his recent tweet, he actually wants the 27-year-old Younger actress to leave him alone.

Seriously.

It all started when Hilary was asked about her ex infamously declaring his love for her on Twitter in a new interview with Cosmo, to which her response wasn't exactly kind.

"Him reaching out through social media? It's ridiculous!" she said. "But then people do it all the time, like Chris Brown and Karrueche [Tran]? Come on, guys. Keep it between text messages."

Shortly after the interview went public, Aaron called out Hilary with this not so thinly veiled tweet on Wednesday.

"Some s**t I just don't get. Stop. Talking. About. It. ... I did," he tweeted.

Last September, Aaron actually admitted that he needed to stop talking about the former Lizzie McGuire star.

"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."
