Amber Portwood's fiance, Matthew Baier, was accused of fathering seven children weeks ago on Teen Mom OG, but there could be much more to the story.

'Teen Mom OG' Amber Portwood Defends Fiance, Claims He Doesn't Really Have Seven Kids

Although Portwood claims Baier is only dad to five children, two of which she spoke of on the MTV reality series, a new report claims he actually has a total of eight children.

On Thursday, in an interview with Radar Online, Baier’s former fiancée, Kelli Maguire Nunn, revealed she has an 8-year-old daughter with the MTV star.

Despite the report, Portwood is convinced Baier has just five children.

“It’s not accurate,” Portwood told MTV, according to a report by Us Weekly earlier this month “He does only have five kids. Yes, I did know about them, but the other ones are older with families, and it wasn’t something that we wanted out.”

“His past was horrible. He wasn’t a good person back then,” she continued. “He was a womanizing user. He was an addict, and that’s not an excuse, but that’s the type of person he was … We went through a rough patch because of this, because I had no trust in him anymore. We had to rebuild our trust again in our relationship.”
