Amber Portwood Goes Off On Baby Daddy In Explosive On-Camera Fight: 'I'm Done!'

Is there already trouble in paradise for Amber Portwood and Andrew Glennon? In a Teen Mom OG sneak peek, Portwood went off on her baby daddy when they disagreed over learning the sex of their first child together.

In the sneak peek, Glennon explained how he would like to wait to find out the baby's gender.

"I want to know what the baby is so I could get prepared," she said. "If it's a boy, I never had a boy. I'm getting stressed out. There is stuff you have to do before you have a baby."

When he insisted on getting "gender neutral" items, she went off on him.

"You don't understand at all," she fired. "It's easier and better to know what the baby is and to prepare."

She continued to yell, "I'm done! What is happening? What is the big deal? I'm pissed off. It's the weirdest argument."

When he asked why she's afraid to learn the sex, she shot back, "I'm not afraid of anything! It's called being prepared. I don't give a s**t about your hippie bulls**t right now!"
