Leah Messer Trying Hard to Quit Smoking

Leah Messer will do anything for her two precious little girls, Ali and Aleeah, and that includes kicking her worst habit.

"I really wanna quit smoking! .. It's such a bad example for my girls," she tweeted this morning.

Leah's tried to quit before, back when she was pregnant with now-husband Jeremy Calvert's baby. She ended up miscarrying, and picked up the cigarette carton once again.

But now, she's determined to try again. 

"#itsanewday to change anything and everything!" she noted.

Mind over matter, Leah!
