Aaron Carter’s father has been left “floored” by his son’s stupidity after he was arrested for marijuana possession in Texas. The singer was pulled over by cops after he was spotted speeding in Kimble County, Thursday.

Police reportedly found two ounces of marijuana during a search of his Cadillac Escalade. Carter’s father, Bob, is hopping mad.

He tells People magazine, “I’m just totally floored by this. Other people suspected he had a problem, but I denied it and didn’t believe it. Now I feel hurt and betrayed, because I see that everything wasn’t what I thought it was.”

A statement from Aaron Carter’s management reads, “On his way to Florida bringing his two dogs to live on a large ranch, Aaron Carter was detained today in Texas by a trooper for exceeding the speed limit by 5 mph. A search revealed a small amount of marijuana, a misdemeanor in this state. He is posting bail and will return to Los Angeles. He sincerely regrets any embarrassment this caused to his family, friends and fans.”

The singer’s father hopes the arrest serves as a wake-up call to his son: “Aaron has always thought he was invincible and sometimes it takes a knock in the head to get people back on track. I hope that’s what happens here.”
