Messer and Corey Simms, the father of her twin girls, have split, according to In Touch.

Corey reportedly withdrew $19K from Leah's bank account to purchase a new truck ... which In Touch claims was the final straw. A source tells the mag:

    "He did it without telling Leah, even though the money is mostly her earnings from MTV. When she found out, they had a vicious fight and she left him.”


As for whether she'll ever take him back, read what the source said ... after the jump.
