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

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

He explains, "She was my first love and actually, I never cheated on her...until towards the end."

Carter and his brother recently came to blows over the fact that Aaron went on a date with Nick's ex Paris Hilton after she and Nick broke up.

Aaron insists that Hilton was the one who asked him out and that he just went to find out information and learned "she wasn't being a good girlfriend to Nick."

Carter recently made headlines when he proposed to Playboy model Kari Ann Peniche after knowing her for less than a week.

The Crazy Little Party Girl singer called off the engagement nine days later when he decided he was too young to marry.

He explains, "I'm just desperate for love, I guess. I keep looking in all the wrong places."
