A Dramatic Timeline of Hilary Duff and Lindsay Lohan's Iconic 2000s Feud

Aaron guest-starred on Lizzie McGuire's Christmas episode. The two started dating on his 13th birthday.

After dating Hilary for nearly two years, the singer started a relationship with Lindsay — at the same time. "I was dating [Hilary] for like a year and a half, and then I just got a little bored so I went and I started getting to know Lindsay," Aaron told CNBC in 2005. Damn.

The "I Want Candy" singer got back together with Hilary and showed up to her big Lizzie McGuire Movie premiere. A few months later, Hilary and Aaron officially called it quits when he allegedly cheated on her (again) with someone else, but that was just the beginning of the actress’s feud with Lindsay.

The girls had a silent red carpet war when they kept popping up at each others' movie premieres. While Hilary attended the Freaky Friday red carpet in April, Lindsay retaliated by showing up to the Cheaper by the Dozen premiere in December.

When Hilary was filming A Cinderella Story, Lindsay reportedly called her Freaky Friday costar Chad Michael Murray — who was playing Hilary's onscreen love interest at the time — to talk trash about her.

During an appearance on TRL, Lindsay was put on the spot when she was asked to confess one thing about herself she wanted to get out in the open and she boldly proclaimed, "I love you, Hilary Duff."

Lindsay poked fun at Hilary during her Saturday Night Live monologue when Rachel Dratch dressed up as an over-the-top version of the singer.

Hilary was not impressed with Lindsay’s SNL stunt. “I’m not here to talk bad about her like she talks bad about me all the time,” she told Access Hollywood while filming the “Our Lips Our Sealed” music video for the A Cinderella Story soundtrack.

Hilary reportedly banned Lindsay from attending the premiere of A Cinderella Story.

Hilary publicly responded to the feud in Blender magazine saying, "Sometimes, I really hate Lindsay Lohan."

Joel Madden, who was dating Hilary at the time, refused to give Lindsay’s 8-year-old brother Cody an autograph at a Good Charlotte concert until she publicly apologized to Hilary.

Lindsay claimed she called Hilary to put the feud to rest, but her sister Haylie answered the phone and hung up.

After letting things simmer down for a few years, the ladies finally put their feud to rest, once and for all. “We are both adults, and whatever happened, happened when we were young,” Hilary told People at the time. “It’s over.” Lindsay was even on hand for the release of Hilary’s album party for Dignity. “She’s really fun,” she said about Lindsay. “We were hanging out the other night, and she’s a nice girl.”
