Hillary Duff at the H&M Launch Party at St olavs School in London

US pop star Aaron Carter admits having cheated on former girlfriend Hilary Duff, even though he insists she was his first and most intense love.

"She was my first love and actually, I never cheated on her...until towards the end," Ratethemusic quoted him, as saying.

Aaron revealed he once went on a date with Nick's ex Paris Hilton, after she broke up with his brother. The teenaged singer also insisted that Hilton was the one who asked him out and that he just went to find out information and learnt "she wasn't being a good girlfriend to Nick."

The 18-year-old is currently starring with brother Nick and their three sisters in the reality TV series House of Carters on MTV. (ANI)
