Aaron Carter, who?

It looks like her ex-boyfriend Aaron's profession of love didn't faze Hilary Duff. The former Disney darling went about her day on Thursday after Aaron tweeted about his admiration for the now single mom.

After retweeting a photo of Hilary (captioned "hilary duff is flawless"), Carter wrote, "Don't be that stupid douche that loses the love of your life forever.. Like me" He then took it one step further by tweeting "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."

The couple dated for almost three years as teens. Hilary broke up with Aaron after he cheated on her with then-rival Lindsay Lohan.

As the pop star poured his heart out on social media, Hilary flirted up a storm with her personal trainer in Beverly Hills. The two were laughing as Hilary's trainer held on to her arm to help her to her car. She drove away with a big smile on her face.

The actress separated from husband Mike Comrie in January, but the pair has remained friends. The two spent Valentine's Day together with their son Luca.
