Nick Carter is apologizing for his bad behavior.

On Jan. 13, the 35-year-old Backstreet Boy was arrested on one misdemeanor count of battery after allegedly getting into a bar fight and appearing "intoxicated" in Key West, Fla. Carter was arrested after the manager of the Hog's Breath Saloon says he saw either the singer or his friend, Michael Papayans, try to punch a restaurant employee. Apparently, the pals were tying one on and had been refused service because they were intoxicated.

Carter has been silent about the hubbub, but has finally spoken out about the incident. On Jan. 23, Carter issued an apology on Twitter, writing, "I am human and at times it can be a struggle to balance a healthy lifestyle. I'm not perfect and for that I am sorry."

The singer added, "When we fall we have to get up and keep on walking. I hope you stay by my side and continue to walk with me."

The "Dancing with the Stars" runner-up is expecting a son with his wife, Lauren Kitt, in the coming months.
