Brown Eyed Girls' Ga In has revealed a strange habit of fellow member Narsha.

On the October 23rd broadcast of SBS' 'Strong Heart', the emcees asked the singer whether the Brown Eyed Girls members have any regulations they follow.

"As we are known for being older [than most girl groups], the members often say they're exhausted after we perform at an event," Ga In said.

The singer then revealed Narsha's method of getting rid of fatigue, saying, "In Narsha's case, she begins drinking beer after we finish [performing at an] event. But the amount of cans she drinks increases the longer it takes for us to arrive at our next destination."

She continued, "The smell of alcohol fills the van. It may be a great atmosphere for those who like alcohol, but it's difficult for those who are unable to drink."

In addition, Ga In revealed the ideal types of each member of Brown Eyed Girls. "We all have different taste in men. Miryo unnie's ideal type is actor Hyun Bin, Narsha unnie likes actor Won Bin, JeA unnie likes Lee Dong Wook, and my ideal type is actor Sul Kyung Goo."
