The year 2000 called: It wants its gossip back.

Hilary Duff and Aaron Carter are making headlines-- yes, you read that right-- because the teen heartthrob of yesteryear has proclaimed his undying love for his former squeeze.

As Lizzie McGuire would say, this is what dreams are made of.

In a well-timed tweet, soon after Duff split from hockey player husband (and father of her almost-2-year-old son) Mike Comrie, Carter posted a present-day photo of her and wrote "Don't be that stupid douche that loses the love of your life forever..Like me..."

Fans immediately went crazy, and who can blame them? This out-of-the-blue throwback transports us to a magical time when hair crimping was socially acceptable and pop stars were so wholesome and sweet they actually sang about candy.

"I'll spend the rest of my life trying to better myself to get back to her," Carter continued. "I don't care what ANY of you think."

Duff has not responded via social media, so there's no telling if this reunion has a shot, but that got us thinking... what other celebrity couples did we never quite get over?
