Eyes On The Road? Leah Messer Texting & Driving With Twin Daughters In The Backseat

Leah Messer lost full custody of her twin daughters, but that doesn't mean she's going to change her bad mom ways! The Teen Mom 2 star was busted texting and driving in a preview clip.

When Messer, 24, picked up her twin daughters from school after they stayed with her ex-husband Corey Simms for the week, she began texting on her phone as she was driving.

Messer continued her monster mom behavior when she yelled at her daughter for slamming her to Simms!

"Do you know what Ali told Daddy?" Aleeah, 6, asked her mom. "You make us get here not late, mommy does."

Messer fired back, "You been getting there on time! Ali, why would you lie like that?"

When Ali didn't respond, Messer continued, "First of all, you guys have no business worrying about what time you get to school. You just need to go to school. Let me and your father handle what time you get to school. Do you understand Ali?"

The mother-of-three then explained how although they don't get to school "when the doors open," they do get there on time.

When Aleeah continued to complain about her twin sister, Messer asked, "You haven't had the best week, have you?"

She cried, "I can't help it. I missed you!"

Teen Mom 2 airs Sunday at 6:30pm on MTV.
