The Transition rapper, who will support Snoop Dogg on tour in October, also insisted that personality is more important than appearance.
He told MSN: "In a girl, I look for self-confidence, ambition, friendliness and someone who's beautiful inside and out.
"There isn't a particular look that I go for. You know, I just like nice people. A nice person will always win me over."
Chipmunk added that although his tattoos attract plenty of female admiration, he did not get them for that purpose.
"I get a lot of female attention about my tattoos, but my look isn't for the ladies, it's more for myself," he explained.
"Rihanna is a real hottie," he said. "I bumped into her in a club when she was having difficulty getting to the toilet because of all the people there.
"So I was a gentleman and helped her get past, not because it was Rihanna, but because I like to have good manners.
"As she went by, she looked up and said, 'Chipmunk!' It was pretty cool that she knew me and she was proper nice. I like the long, red hair, though she's even better with it short."
