Hilary Duff
Hilary and Aaron met at Aaron's 13th birthday party in December of 2000. In 2001 they met up again to do an episode of Lizzie McGuire together.(Aaron Carter is comin to town) They went out for about 2 years after that but broke up cuz they hardly got to see each other. Recently at the Lizzie McGuire Movie premiere, they met up AGAIN and I guess started goin out again. A few weeks ago, Hilary's sister Haylie said in an interview that Aaron and Hilary aren't going out anymore.. so who knows!
Lindsay Pagano
Lindsay was an opening act for Aaron's Winter Party tour. They went out for awhile but broke up cuz they weren't right for each other..
this came from a magazine clipping
Lindsay and Aaron dated.
Ah, the world of young love and teen crushes. Aaron Carter and Lizzie's Hilary Duff had just broke up when the pop star began crushin on singer Lindsay Pagano. The Aaron/Hilary relationship may have faltered cause their busy work schedules kept them apart, but Aaron and Lindsay had lots of time together when she joined his tour early this year. Thats where the relationship really blosommed, admist Lindsay, adding that they spent their free time hiking, shopping, and listening to music. "We were really interrested in each other, but we're not together anymore" Lindsay says. "Its just really hard to be on tour with somebody you're dating. We're gonna hold off [dating] for a while."
