Leah, now 27, confessed that she aborted her baby because she was conflicted over her relationship with ex-husband Corey Simms.

After her split from her first ex-husband, Leah started dating Jeremy even though she "definitely wasn't over him."

Leah and Corey share twin daughters, Ali and Aleeah.

After Corey learned that Leah was in a relationship with Jeremy, he had "second thoughts" about divorcing and they discussed giving their marriage another chance.

Even though Leah was "twisted up in knots" over her first ex-husband, she moved in with Jeremy and the two got engaged.

She learned she was pregnant with their child just weeks later.

In the book, Leah wrote: "I was devastated. Having a baby with Jeremy would be the end of any chance Corey and I had of making things work for our family. I was sad for myself, but mostly I was sad for our girls. I knew I had f**ked up, and I felt like I had ruined their lives on top of mine.”

Leah also claimed in the book that her rep at the time encouraged her to terminate the pregnancy to help save her “public image.”

Leah's mom, Dawn, she she would "support" whatever decision she made, but Jeremy couldn't find out if she decided to terminate the pregnancy.

Dawn and rep “came up with a plan” to make it look like Leah was “having a miscarriage.”

The MTV star claimed in the book that she took pills from a clinic, and started having heavy bleeding and cramping.

Leah wrote in the memoir: “When she told him I was having a miscarriage the way she played the role of concerned mother was so damn convincing even I couldn’t tell she was lying.

“I remember listening to her talking to Jeremy on the phone and wondering how the hell I had let this happen.”
