'Teen Mom 2' star Leah Messer has filed for divorce from the father of her twin girls just six months after their wedding, UsMagazine.com reports.

Though Messer, 18, and Corey Simms, 20, ended the 'Teen Mom 2' season with a wedding celebration, it hasn't always been easy for the young couple, who found out they were expecting twins after just one month of dating.

"Everything Corey and I have done has happened so fast," Messer told Us recently. The pair have had a rocky relationship, including breaking up even after their daughters, Aliannah and Aleeah, now 16 months, were born.

The pair reconciled, got engaged and married last October, all in front of the MTV cameras. However, Messer expressed some concern that they were moving too quickly.
