It appears Aaron Carter is not happy with ex-girlfriend Hilary Duff following comments she made in an interview with Cosmopolitan. The actress, who appears on the cover of Cosmo’s April issue, addressed comments Carter allegedly made about wanting her back following her initial split from husband Mike Comrie.

"Some sh*t I just don't get. Stop. Talking. About. It. ...I did," he tweeted after the interview came out.

Carter and Duff dated for nearly three years starting in 2000. The pair called off the relationship after rumors of Carter’s infidelity began swirling. The former “Lizzie McGuire” star married her NHL player husband in 2010. They share one child, a son named Luca. Unfortunately the marriage hit a rocky patch, leading to a separation in 2014.

After learning of the split, Carter seized the opportunity to let the Twitterverse know he still had feelings for his former love interest.

"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," he added.

The Twitter love confessions didn’t end there. Carter continued to advertise his feelings until last September before admitting that it was time to “shut up.”

“She’s got a kid and she’s married and I’m not trying to be that dude,” he said, according to Us Weekly. “That’s not my intention.”

During her interview with Cosmopolitan, Duff said she found the entire thing to be “ridiculous,” though she noted that it was not necessarily out of the ordinary in this day and age.

“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.”

Duff also went into great detail about her recent decision to file for divorce from Comrie, ending their five-year marriage once and for all. She and her husband gave their marriage a second chance, getting back together in April 2014, according to Celebuzz. Unfortunately their effort was not enough.

TMZ reported that Duff had officially filed for divorce from her husband of five years on Feb. 20, citing irreconcilable differences. The actress-turned-pop star says although the pair were crazy in love when they met, the decision to marry may not have been the right one.

“Mike and I were very in love when we met,” she said. “We both really wanted to get married. I’d been working since the age of 11 or 12, so making that choice at a young age seemed right for me. Maybe it wasn’t, but we spent the majority of our time together really happy.”

Those memories of happy times were not enough to save the marriage. The 27-year-old told Cosmo it took time to accept the reality that she and the man she believed to be the love of her life were not meant to be.

“It wasn’t working well enough to stay together, but there was still a lot of love involved,” she said. “It was just a slow set-in of us not being the match that we used to be. I’m lucky for the person he is and I am and how we decided to handle this.”
